连续体平面应力的有限元算法

在研究平面应力问题时,工程中使用的形状复杂的连续体很难用经典的力学计算求得解析结果,而应用有限元法将能够求得满足工程精度的近似解。本文以受压正方形板的应力分布为例,说明了有限元法在平面应力计算中的具体应用,该应用实例表明了有限元法在工程中用于求解连续体应力问题的重要性。

Research on Plane Stress Computations for Continuous Body Based on Finite Element Method

For the plane stress computation problem in engineering,it is difficult for continuous body of complex shape to find the resulting solution using the classical mechanics method.However,the approximate solution to meet accuracy can be found applying the finite element method.In this paper,taking the square board in pressing as an example,the specific application of finite element method for the plane stress computation is described.Such an example shows the importance of finite element method for solving the...
