Finite element analysis method on stress
Thread Content
I have read a lot of finite element analysis methods about stress, but I have never done it, and I have never seen anyone else do it. I would like to ask the experts, how do you do this?
Finite element analysis is the use of finite element methods to analyze static or dynamic physical objects or physical systems. In this method, an object or system is decomposed into a geometric model composed of multiple interconnected, simple, independent points. In this method the number of these independent points is limited and hence it is called finite element. The equilibrium equations derived from the actual physical model are applied to each point, resulting in a system of equations. This system of equations can be solved using linear algebra. The accuracy of finite element analysis cannot be improved indefinitely. After the number of elements reaches a certain height, the accuracy of the solution no longer increases, only the calculation time continues to increase. The key to finite element is meshing! If the division is done well, the calculation will be simple, otherwise there will be no solution. (Repost)
