Thermal effects on dynamic response of GOP-Reinforced beams under blast load

This article has been devoted to investigate the dynamic response of a graphene oxide powder (GOP) reinforced beam exposed to blast and thermal loads. It is assumed that the blast load has been exerted on the top surface of the beam. The material modeling of GOP-reinforced composite has been performed assuming two types of GOP distribution called uniform and graded in thickness direction. The establishment of the governing equations has been done employing a refined shear deformation beam theory and the consideration of elastic foundation. Finally, the equations have been solved implementing Chebyshev-Ritz method and inverse Laplace transform method. Then, the time history of the beam has been derived and its dependency on GOP percentage, GOP distribution, temperature rise, blast load factor, foundation coefficient band load position.
