A Numerical Solution of Symmetric Angle Ply Plates Using Higher-Order Shear Deformation Theory

This research aims to provide the numerical analysis solution of symmetric angle ply plates using higher-order shear deformation theory (HSDT). The vibration composite is analyzed differential equations consisting supplanting and turning functions. These functions are numerically approximated through spline approximation. obtained global eigenvalue problem solved find eigenfrequency parameter a related eigenvector coefficients. different constituent components used study parametric effects plate’s aspect ratio, side-to-thickness assembling sequence, number layers, alignment each layer on frequency plate. results validated by existing literature.
