Elastic Modulus (E)
It is the constant of proportionality between stress and strain.
It represents the slope of the elastic portion of the stress – strain curve.
It is a measure of rigidity or stiffness
Materials with higher Young’s modulus value are said to be stiffer or more rigid than those of low Young’s modulus values because they require much more stresses to produce the same amount of strain.
It is measured by stress/strain.
It is measured by GPA=109 Pascal.
