A linear elastic, isotropic epoxy resin with elastic modulus, E=2GPa, and Poisson’s ratio, ν=0.3, is loaded by the following stress state:
σ=⎡⎣10 5 0
5 −20 0
0 0 0⎤⎦MPa
Give numerical values for all strain components in the corresponding strain matrix.
Give a numerical value for the elastic strain energy, U, in the resin in terms of J/m3.
U in ( J/m3):
σ=⎡⎣10 5 0
5 −20 0
0 0 0⎤⎦MPa
