Experimental and numerical investigation of static and free vibration responses of woven glass/epoxy laminated composite plate

Abstract

In this article, the static and the free vibration behavior of laminated woven glass/epoxy composite plate have been investigated numerically and validated through subsequent experimentation. The laminated composite shear deformable plate has been modelled mathematically using two different higher-order kinematic theories and the commercial finite element package (ANSYS). The domain has been discretized using the finite element steps and the desired responses (deflections and frequencies) are computed numerically using homemade computer code developed in MATLAB environment. The validity and the convergence behavior of developed models have been established by comparing the responses with those available published literature, simulation and the corresponding experiment. Finally, the effects of geometrical and material parameters (thickness ratio, modular ratio and support conditions) and the necessity of higher-order model for the analysis of laminated structure have been highlighted by solving wide variety of static and vibration examples.
