三维粱单元有限元计算内核，用VC++编写-engine for finite element analysis with the 3-d beam element, coded with VC++

本程序采用平面梁单元计算两铰抛物线拱的自由振动特性，希望对学习有限元及程序设计有帮助。-The program uses two hinged planar beam element calculation of the free vibration characteristics of the parabolic arch, the finite element and want to learn programming help.

利用有限元理论，求一二维梁的固有频率和振型。短边固定，给定长度、横截面积，弹性模量及材料密度已知。并对比理论计算结果进行分析。各参数自己设定。-Using finite element theory, seeking a two-dimensional beam natural frequencies and modes. The short side is fixed, given the length, cross-sectional area, modulus of elasticity

以三角形网格为实例，采用有限元法计算悬臂梁的应力分布(Taking the triangular mesh as an example, the stress distribution of the cantilever beam is calculated by the finite element method)

Matlab编写的梁杆单元的有限元分析，分析应力、应变。(The finite element analysis of beam column element written in Matlab is used to analyze stress and strain.)
