  • 基本概念 ( Concept )

4节点四面体线性“完全积分”单元,用Abaqus中的命名规则,即 C3D4。

  • 问题描述( Problem Description)

悬臂梁,悬臂长度2.0m,梁高0.5m,梁宽0.2m。梁左端嵌固,受重力作用。材料弹性模量E=200000MPa,材料泊松比为0.3。

基于MATLAB编程实现该悬臂梁的弹性静力分析,采用C3D4单元进行模拟,并将MATLAB的计算结果与Abaqus、midas Gen分析结果进行对比。

  • MATLAB 编程

MATLAB编程计算结果是和 Abaqus及 Midas Gen的计算结果是完全一致的。
