Finite

Three main ways to derive finite element equations. 1. Direct method or Direct equilibrium method for structural analysis problems 2. Energy Methods and principle of virtual work 3. Weighted Residual Methods Of the three methods, the direct method is the simplest and can clarify the physical understanding of the FEM. However, it is limited to finding the stiffness matrix of a one-dimensional ele..

I remembered that in my previous post(13_Pendulums) I said that I would explain the Finite Element Method(FEM) later. 13_Pendulums There are a lot of interesting examples in the RADIOSS example, so I'll be working through them for a while. In this post, I'll going to perform a Pendulums example. There was also an example file in HyperMesh's installation path. However, due to the diffe finite-ele..
