چکیده انگلیسی
In the present research, impact analysis of rectangular composite plates with embedded SMA wires is accomplished through including the following items for the first time: (1) the layerwise impact-induced temperature-rise (2) effects of the ambient/impact-induced temperature-rises on the material properties and the direct and converse phase transformations, (3) transverse flexibility of the layers, (4) a refined layerwise description of the displacement field, employing virtual sub-layers, (5) a modified constitutive law for the SMA wires, (6) effects of stiffness of the lower layers on the stiffness of the contact region, (7) considering the shape memory effect in addition to the pseudo-elastic nature of the SMA wire, and (8) partially verifying the results based on experimental results extracted by the authors. The coupled thermoelasticity and impact governing equations of the indenter-plate system are determined by means of a combined Galerkin-Energy finite element approach and solved by means of an updating-based Newton-Raphson procedure. Present results show a good concordance with the experimental results. Results reveal that the impact-induced temperature-rise and temperature-dependency of the material properties increase the start and finish stresses of the direct and converse phase transformation mechanisms and lead to larger hysteresis loops, strains, and stresses in the SMA wire.
