Explicit stiffness matrices for triangular, plate bending finite elements
… stiffness matrices are available for rectangular plate bending elements, rectangular plane stress and plane strain elements and triangular plane stress and plane strain elements. Triangular plate bending elements can at present only be formed by using a numeric algorithm. The explicit version of a …

Implementation of a python version of a scaled boundary finite element method for plate bending analysis
Common finite element programs for plate bending analysis are complicated and limited by the common plate theories. Such programs are usually not user-friendly for designers to implement. Lately, Hou Man et al. from the University of New South Wales has developed a technique for unified 3D plate …

Transient analysis of layered composite plates accounting for transverse shear strains and von Karman strains
… and accurate procedure for performing transient bending analysis of laminated composite plates. Classical theory is inadequate because it neglects transverse shear deformation, rotatory inertia, and geometric nonlinearities. In this thesis, a theory to account for transverse shear deformation and …
