What is axial modulus?

Axial modulus, also known as the axial stiffness or longitudinal modulus, is a measure of a material's resistance to deformation under axial loading. It is defined as the ratio of axial stress to axial strain within the elastic limit of the material. A higher axial modulus indicates that the material is stiffer and less prone to stretching or compressing when a load is applied. This property is crucial in engineering and materials science for assessing the performance of structural components.
