Abstract

In the present study, flexural behaviour of laminated composite plate with porosity presented using improved third-order shear deformation theory. Present theory ensures transverse shear stress continuity at each layer interface in addition to zero transverse shear stresses at top and bottom of plate. C0 finite-element (FE) formulation developed of the present theory. This is the first attempt to study the laminated composite plate with porosity using the present advanced theory. The present improved third-order theory incorporating transverse shear stress continuity at each layer interface predicts better results than third-order shear deformation theory and first-order shear deformation theory. Authors for the present study developed an in-house FORTRAN code. The effects of material properties, orientation angle of the fibre, and sequence of laminated plate with porosity on stresses and deflection are studied. The comparison with the existing literature predicts the accuracy and robustness of present work.
