MFEM Tutorials (3) Simple Linear Elasticity Problem Describing a Multi-Material Cantilever Beam Part A
Description This example code solves a simple linear elasticity problem describing a multi-material cantilever beam. Specifically, we approximate the weak form of where is the stress tensor corresponding to displacement field $\textit{\textbf{u}}$, and lambda and mu // are the material Lame constants. The boundary conditions are $\textit{\textbf{u}}=0$ on the fixed part of the boundary with…
