EAS4200C Aerospace Structures Homework #3 (Due: Sep. 25th) 1. For small strains, the volume change Δ V / V is identified to be equal to ε xx + ε yy + ε zz . The bulk modulus K of an isotropic solid is defined as 1 () 3 xx yy zz V K V σσσ Δ ++ = Drive K in terms of E and ν . 2. A block of elastic solid is compressed by normal stress σ xx as shown in the figure. The containing walls are rigid and smooth (frictionless). Find the values of
