若干复合材料计算机程序评介

由于复合材料结构件的各向异性和层合性,使得复合材料结构的设计、分析要比金属复杂得多,工作最也要大得多,有些工作甚至是手工计算所不能胜任的,必须依靠计算机。因此,近十几年来复合材料的计算机程序迅速地被开发出来。虽然列入《复合材料设计手册》的程序有36个,但在编写过程中涉及的程序有60多个。本文仅就其中的一些做一粗浅的评介。

A REVIEW OF SOME COMPUTER PROGRAMS OF COMPOSITES

The computer programs of composite materials for aviation structure are brieifly reviewed. Some computer programs for linear and nonlinear static analysis, stability analysis, vibration, flutter, optimum design and imported computer programs are involved. The advantages, distinguishing features, drawbacks and future improved a spect of these computer programs are pointed out. The situation about application and appraisal of these computer programs are introduced. It is suggested that these existing computer programs should be spreaded and used. In this paper some respects of new developed computer programs, for example coupling effect, hygrothermal effect, interlaminar stress, impact damage etc., are put forward. It is a special important respect that now available large-scale computer programs should be improved, perfected and added with some operating function about composite materials. This method will not only save time and labour power but also save large financial resources.
