✦ Synopsis

Abstract

A method of formulating and computing numerically integrated stiffness matrices is presented. Through a better organization of the formulation which is easily achieved by the use of index notation, the computations for integrating and evaluating the element stiffness matrix are substantially reduced. For cases in which the terms of the material property tensor are not functions of position co‐ordinates (elastic isotropic and anisotropic materials), a further reduction in computation is achieved by multiplying the material property‐tensor after the numerical integration has been carried out.
