Why is it Important to Study Stress and Strain?

When you are talking about solids and various other materials, it is crucial to understand how these types of materials usually react when a force is applied. This process helps the students identify their strengths, deformations, and various other parameters acting on the objects. And to find these parameters, the stress and strain quantities are important. Here, in this article, we are going to provide a detailed guide about these aspects including how we define stress and strain, their types, and difference between stress and strain. Also let us learn about stress formula and strain formula.

Why is it important to study stress and strain?
It is important to study the stress and strain curve differences and basics, and stress strain curve, all of which will help in ascertaining the amount of stress or load that a material is capable of handling before it breaks, gets distorted, or stretches. So, the study of stress and strain is all about understanding how and why certain materials are more malleable and can be easily deformed or distorted than others.

Stress is defined as the force per unit area that is observed by a material when an external force is applied. These external forces are generally uneven heating, permanent deformation, etc.

Types of Stress
There are different types of Stress that can be applied to a material, such as

Compressive Stress
When a force acts on a body, it causes a reduction in the volume of the said body, resulting in deformation. This type of stress is referred to as Compressive stress.

Compressive stress leads to material failure that is ultimately caused due to tension. The compressive stress from its application to brittle materials differs from that of ductile materials.

Tensile Stress
When an external force is applied per unit area on a material, and it results in the stretching of the said material, then it is described as Tensile Stress.

Tensile stress leads to elongation of any material due to external stretching force.

If a body experiences deformation due to the applied external force in a particular direction, it is called strain. Moreover, the strain does not have any dimensions, as it only explains the change in the shape of the object.

Types of Strain
Similar to stress, strain is also differentiated into Compressive Strain and Tensile Strain.

Compressive Strain
Compressive strain is defined as the deformation observed on an object when compressive stress acts on it. And in this type of strain, the length of the material or object generally decreases.

Tensile Strain
The Tensile stress acting on a body or a material that causes the increase in the length of said material is referred to as a tensile strain.

The stress-strain curve typically consists of several distinct regions:

Let us understand stress-strain curve as we try to understand the stress-strain graph better through various regions:

Elastic Region: In this region, the material deforms elastically in response to applied stress, meaning it returns to its original shape once the stress is removed. The relationship between stress and strain is linear, and this region is characterized by Hooke’s Law, which states that stress is proportional to strain.

Yield Point: Beyond a certain stress threshold known as the yield point, the material begins to deform plastically, meaning it undergoes permanent deformation even after the stress is removed. The yield point marks the transition from elastic to plastic deformation.

Plastic Region: In this region, the material continues to deform plastically with increasing stress, undergoing significant strain without a proportional increase in stress. Plastic deformation is irreversible, and the material’s shape changes permanently.

Ultimate Tensile Strength: The ultimate tensile strength (UTS) is the maximum stress that a material can withstand before failure occurs. It represents the highest point on the stress-strain curve and indicates the material’s resistance to fracture under tension.

Fracture Point: Beyond the ultimate tensile strength, the material experiences a rapid decrease in stress leading to fracture or failure. The fracture point marks the end of the stress-strain curve, indicating the material’s ultimate failure under tension.

Difference between stress and strain
In physics, stress refers to the force that is acting per unit area of the object, whereas strain depicts the ratio of the change in an object’s dimension to its original dimension. In physical parlance, stress is equivalent to Pressure and its unit is Pascal or psi, or pounds. On the other hand, strain signifies the ratio of change in dimensions to that of the original dimension, therefore has no units of measurement. Strain, however, can be measured by strain gauges.

Stress and strain are related, but are characterised by distinct properties. Stress causes deformation, while strain can be caused by several types of stress, including tension or compression.

Health as a Career!

Viewing your health as a career and managing it as such my be one of the most important things you can do for yourself.

mediaimage
The term ‘career’ is most often thought of in the context of a profession or occupation, but dictionaries also apply the term to a chosen pursuit – a person’s progress or general course of action through life or through a phase of life.

If we use the latter part of the definition, then things like education, home-making, marriage, family relationships, many leisure pursuits like sailing or gardening can also be considered as careers in their own right along with work and profession.

Most of us strive to be successful in our pursuits. While the term success is somewhat subjective, it usually involves the attainment of one or more goals that we establish for ourselves, or should establish relative to our careers.

To achieve those goals, many things have to happen but as a minimum the following three things are usually required:

First, the goals must be thought out, formally or not, and established. You have to think through what you want to achieve and how successful you want to be with regard to each career you pursue.

Second, the goals must be worked towards. You have to apply both time and effort towards attaining those goals. That includes learning, acquiring, developing and applying all necessary expertise, skills and experiences. It also means applying the necessary amount of time.

Thirdly, you must be able to measure your progress and degree of success. You do this so that you can determine where you are on the path to your goals and so that you can change your goals or your approaches as required.

In short, your various careers have to be managed.

If we accept that in many cases we have more than one career on the go at the same time, and most of us do, then the issue of balance also comes into play. How do we decide how much time and effort should be applied to one career versus another?

It is not unreasonable to expect that if we apply all of our time and effort to one career, then it is likely that others will suffer as a result. That means that we must somehow find a way to rank our various careers in terms of relative importance to us, and find a way to balance the time and effort we expend on each accordingly such that the goals are achieved for each. A person who spends all of his or her time and effort on an occupational career may well find that another career is suffering – say a marriage or a golfing hobby. Conversely, spending every day on the golf course may have a detrimental affect on one’s occupation and marriage careers. Look around and view the careers of people you know to see the effects of this reality. Take a hard look at how you are managing your own careers and at how successful you are with each.

Not an easy task for sure, this career business.

Now, let’s complicate things a little further by suggesting that we have another career that requires management – that is, time and effort. That career is our health.

Yes, health!

While success, happiness, wealth and any number of other things are important in all of your other careers, they will not mean very much if you don’t have your health. It is a critical component of our lives and its pursuit has to be managed just like anything else. It is a career in its own right, and perhaps the most important.

If you accept this premise, it means that you have to:

First, set goals relative to your health – things like weight, blood pressure, diet and body mass index levels.

Second, you have to apply both time and effort working toward those goals – appropriate levels of exercise, proper diet and levels of substance and food ingestion.

Thirdly, It means you have to measure your progress and be prepared to alter your goals and approaches as required.

In other words, you have to approach your health in the same way that you approach any other career you want to be successful at. It has to be managed.

If you accept this premise, then the issue of balance comes up again. How much time and effort should I put in to managing my health relative to my other careers?

You are the only one who can answer that question. No one can do it for you. You are the only one who can decide that your health is as important if not more important that any of your other careers. You are the only one who should be setting goals relative to your health. You are the only one who can measure how you are doing in the pursuit of those goals. In other words, you are the only one who can manage your health. No one else can, nor should you expect them to – it is your responsibility.

We can even take this health career premise further by positing that if you manage it successfully you will have a greater chance of success in most if not all of your other careers.

For ideas on the types of things you can do to better manage your health, you may be interested in other articles I have published on the subject. There are several of them because I personally think of the management of my health as a career and I try as best I can to manage it as such.
