Static Analysis for Stress Concentration Due to Elliptical Notches of Laminated Plates

In the present paper, stress concentration factors (SCF) of sandwich plates with elliptical notch at corner subjected to out plane load are studied. The mathematical modeling of the present problem is done using secant function-based shear deformation theory (SFSDT) with geometrical nonlinearity. Minimum potential energy method is used to derive the bending governing equation. Influence of cutout dimensions, fiber orientations, plate span to thickness ratios, and boundary conditions are investigated using a MATLAB program. The present outcomes are compared with the outcomes of already published work.
