The post-yield behavior of the metal and matrix are as follows: The metal is ductile and undergoes some strain hardening in the plastic regime. The strain to failure of the metal is 0.4 and the ultimate tensile strength and fracture strength of the metal are 320 MPa. The epoxy exhibits a more brittle like behavior - the stress does not increase after reaching yield and thus the ultimate tensile strength and fracture strength of the epoxy are equal to the...
