Transient thermo-viscoelastic memory-dependent responses of the temperature-dependent laminated polymethyl methacrylate composites with imperfect interfaces subjected to laser pulse heating.

AbstractThis paper aims to investigate the transient thermo-viscoelastic memory-dependent responses of the temperature-dependent laminated polymethyl methacrylate (PMAA) composites with imperfect interfaces, of which the bounding surface subjected to non-Gauss laser heating loads, are investigated based on integral-type non-Fourier thermo-viscoelasticity model with memory-dependent derivative (MDD). The Laplace transformation is used to solve the multi-physics differential governing equations. The influences of the viscoelastic material constants ratios, temperature-dependent parameters, laser parameters, memory-dependent parameters and kernel functions on the responses are elucidated to offer guidelines to thermal control and mechanical strength evaluation for the laminated PMMA composites.
