Inverse identification of process-induced shrinkage strain for a B-stage thermoset resin in woven pre-impregnated lamina via warpage analysis

Multilayer composites are often found in industrial applications where pre-impregnated (pre-preg) and laminated plies are stacked and hot pressed. Along this process, the B-stage resin within pre-pregs cures and shrinks, generating residual stresses in the assembly which need to be quantified. The B
