Proportional Limit in Stress-Strain Curve
Definition: The proportional limit is defined as the point on a stress-strain curve where the relationship between stress and strain is no longer linear.
Explanation:
When a material is subjected to an external load, it experiences deformation or strain. The relationship between the applied load or stress and the resulting deformation or strain is represented by a stress-strain curve.
In the initial stage, the stress-strain curve is a straight line, indicating a linear relationship between stress and strain. This linear region is known as the elastic region of the material where the deformation is recoverable upon removal of the load.
As the load or stress is increased, the material undergoes plastic deformation and the stress-strain curve deviates from the linear path. The point on the stress-strain curve where the deviation from the linear path occurs is known as the proportional limit.
At the proportional limit, the material starts to yield and undergoes permanent deformation. The material can no longer return to its original shape after the load is removed, indicating that the material has reached its yield strength.
Importance:
The proportional limit is an important parameter of a material's mechanical properties. It indicates the maximum stress a material can withstand without undergoing permanent deformation. Therefore, it is important to determine the proportional limit of a material to select the appropriate material for a given engineering application.
