Category: FEA Theory

Last article is in my series on basic FEA theory. In this article I put everything together to solve for the displacements.

This article is part 4 in my series on basic FEA theory. The focus is on how to calculate the element stiffness matrix.

The article shows how to calculate the strain components from the nodal displacements in a linear finite element calculation.

The focus of this article is on how isoparametric shape functions can be used to simplify the calculation of the principle of virtual work.

Derivation of the equation of virtual work in discretized form. The presented results are the foundation to the Finite Element method.

Tutorial on how to write a full FE solver in 200 lines of Python code. This is part 2 in our series. The focus is on using an external file.

Tutorial on how to write a full FE solver in 100 lines of Python. This is part one of this tutorial series.
