A high precision triangular laminated anisotropic shallow thin shell finite element

Abstract

A high precision triangular laminated shallow thin shell finite element has been developed based on the classical lamination theory. The stiffness matrix is obtained explicitly by pre and post multiplying a few basic matrices. The formulation is almost an order of magnitude faster than those available for similar order elements. The numerical results of the example problems presented demonstrate that both displacements and stresses are predicted accurately with moderately coarse grids. A complete listing of FORTRAN subroutines is presented for users, to ease implementation of the algorithm. © 1985.
