Calculate the Modulus of Elasticity E in ksi for a test coup

Calculate the Modulus of Elasticity, E in ksi for a test coupon subjected to pure tension that resulted in stress = 108 ksi and strain = 0.003.

Solution

By the definition of modulud of elasticity:

Modulus of Elasticity = stress/strain

= 108/0.003

=36000 ksi (Strain does not have any units)
