Fibre Composite Laminated Plate Analysis Using a Card Programmable Calculator (HP 41C/CV)

摘要

The HP 41C/CV programs which perform the stiffness and strength calculations for composite laminates are presented. Two sets of programs are given, each to be used interactively: (1) symmetric laminates or sandwich beams comprising one type of ply material only; and (2) general laminates comprising up to three different ply materials. The programs include nonmechanical effects. The strength ratios (reserve factors) calculated are for first ply failure (FPF) and are based on mechanical strain. Behavior beyond FPF is not included. Classical lamination theory (CLT) is used.
