It commonly believed that the stress concentration factor for a plate with a hole in uniaxial tension is 3. This not true!
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 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.
