EAS4200C Aerospace Structures Homework #3 (Due: Sep. 25th) 1. For small strains, the volume change ΔV/Vis identified to be equal to εxx+ εyy+ εzz. The bulk modulus Kof an isotropic solid is defined as 1()3xxyyzzVKVσσσΔ++=Drive Kin terms of Eand ν. 2. A block of elastic solid is compressed by normal stress σxxas shown in the figure. The containing walls are rigid and smooth (frictionless). Find the values of
