Static and dynamic response analysis of sandwich plates having corrugated core under patch loading is presented in this paper. In this work, the problem formulation is made using finite element-based higher shear deformation theory. The influence of various parameters like aspect ratio, corrugated plate thickness, core thickness, corrugation angle, boundary conditions, ratio of face thickness to corrugation plate thickness on transverse deflection, stresses, and dynamic bending responses are revealed. In the present investigation, a MATLAB program is developed with nine nodded seven degrees of freedom per node of element. The obtained results are verified with available results in the literature to check the program’s efficiency. It is found that transverse deflection increases with increase in corrugation angle, and maximum rotation about the ‘x’ and y-axis increases with increase in the area of the plates exposed to patch loading. Edge constraints have a significant effect on transverse deflection and stress.
