What is the relationship between stress and strain?

What is the relationship between stress and strain?

Stress is the force applied to a material, divided by the material’s cross-sectional area. Strain is the deformation or displacement of material that results from an applied stress.

Do stress and strain have a linear relationship?

This linear, elastic relationship between stress and strain is known as Hooke’s Law. If you plot stress versus strain, for small strains this graph will be linear, and the slope of the line will be a property of the material known as Young’s Elastic Modulus.

Are stress and strain inversely related?

Therefore, stress and strain are directly proportional to one another, a relationship first discovered by Robert Hooke (1635–1703) and now referred to as Hooke’s law. Stress is directly proportional to strain. Beyond the elastic limit, the material remains deformed even when the stress is removed.

Are stress and strain directly proportional?

Hooke’s law: It States that under direct loading, within proportionality limit, stress is directly proportional to strain.

How do you explain stress strain curve?

A stress-strain curve is a graphical way to show the reaction of a material when a load is applied. It shows a comparison between stress and strain. Stress is the ratio of the load or force to the cross-sectional area of the material to which the load is applied.

Can you have stress without strain?

Stress can happen with out strain, but strain cannot happen without stress.

How do you explain stress-strain curve?

Is the maximum stress at which stress is directly proportional to strain?

Proportional Limit
1. Proportional Limit – This is the highest stress at which stress is directly proportional to strain. 2. Elastic Limit – This is the greatest stress the material can withstand without any measurable permanent strain remaining on the complete release of the load.

What is the maximum stress at which stress is directly proportional to strain?

Which point on the stress strain curve occur just after the proportionality limit?

Which point on the stress strain curve occurs after the proportionality limit? Explanation: The curve will be stress strain proportional upto the proportionality limit. After these, the elastic limit will occur.

What is elastomers explain with stress strain curve?

An elastomer is a polymer with viscoelasticity (having both viscosity and elasticity) and very weak inter-molecular forces, generally having low Young’s modulus and high failure strain compared with other materials. The term, which is derived from elastic polymer, is often used interchangeably with the term rubber.
