What is the value of υ21 if the values of E11, E22 and υ12 are given by E11 = 138GPa, E22 = 10GPa and υ12 = 0.21?

What is the value of υ21 if the values of E11, E22 and υ12 are given by E11 = 138GPa, E22 = 10GPa and υ12 = 0.21? Correct Answer 0.0152

Given that, E11 = 138GPa, E22 = 10GPa and υ12 = 0.21 We know that, υ21 / υ12 = E22/E11 ⇨ υ21 = (E22/E11) * υ12 ⇨ υ21 = (10/138) * 0.21 ⇨ υ21 = 0.0152.
