Difference between elastic limit and tensile strength

Main difference

Before differentiating between yield strength and tensile strength, one should be aware of terms like stress and strain, as the main concepts of both terms underlie both strengths. The applied force can deform objects, stress and deformation are interrelated and have a strong connection with deforming forces. Stress is the measure of the deformation force per unit area of ​​the body, while stress is the relative change in the length of the body due to deformation forces. Stress has a unit similar to that of pressure, Pascal (Pa), while in the deformation where it is a change in length, it is indicated as the percentage change in the length of the body due to the deformation force. It is worth mentioning that the greater the tension on the object, the greater the tension. Following these concepts, the elastic limit is the minimum stress under which the object carries a permanent deformation, while the tensile strength is the maximum stress that an object can withstand before breaking or collapsing. The deformation we are talking about here is deformation and it is caused by stress on the surface of the object.Elasticity is another related term as it is the ability of the object to withstand the stress and make the object return to its state original. while the tensile strength is the maximum stress that an object can withstand before breaking or collapsing. The deformation we are talking about here is deformation and it is caused by stress on the surface of the object.Elasticity is another related term as it is the ability of the object to withstand the stress and make the object return to its state original. while the tensile strength is the maximum stress that an object can withstand before breaking or collapsing. The deformation we are talking about here is deformation and it is caused by stress on the surface of the object.Elasticity is another related term as it is the ability of the object to withstand the stress and make the object return to its state original.

What is the elastic limit?

When the object is placed and no external force or stress is applied to it, there is no change in it. Actually, the applied stress causes deformation in the object, while the other forces can change its motion from static to kinetic or vice versa. The applied tension does not produce the change quickly, it depends on the nature of the object and the tension applied to it. At first, when stress is applied, it appears that the object has been deformed, but it returns to the actual shape or size, that is due to the elasticity of that object. Although at a given moment, when stress is applied, the object is permanently deformed and does not return to its original position. The minimum stress under which the object leads to permanent deformation is the elastic limit.

Tensile strength?

The concept of tensile strength also revolves around stress and strain and is the point that comes after the elastic limit. When stress is applied to the object and it is permanently deformed, it is the elastic limit, although when stress is applied even after deformation of the object, there comes a point where the object breaks or collapses. Tensile strength is the maximum stress that an object can withstand before breaking or collapsing. For example, a rubber band has one of the highest tensile strengths as it has more elasticity, which means it can withstand more stress before collapsing. When stress is applied to the rubber band, it is deformed or stretched for a long time, but eventually the time comes when it breaks.

Yield strength vs. tensile strength

  • Stress is the measure of the deformation force per unit area of ​​the body, while stress is the relative change in the length of the body due to the deformation forces.
  • The elastic limit is the minimum stress under which the object leads to permanent deformation, while the tensile strength is the maximum stress that an object can withstand before breaking or collapsing.
  • Elasticity is another related term, as it is the ability of the object to withstand stress and make the object return to its original state.
