Method for Computer Simulation of Problems in Solid Mechanics and Gas Dynamics in Three Dimensions and Time.

摘要

Details are given for a versatile computer program that employs finite element and finite difference techniques to describe complex physical phenomena in three dimensions and time. Applications include problems in gas dynamics, elasticity, dynamic plasticity, fracture, and thermal conduction. The main features of the program are illustrated by a calculation that determines the thermal-shock stresses in a stator blade of a gas turbine engine. Appendices present an outline of SOLID SAP, a complete mathematical development of HEMP 3D, a comparison between finite difference and finite element methods, and descriptions of subroutines for discretizing, for display, and for calculation of three-dimensional thermal diffusion.
