About this document

CST vs. LST Element Comparison by Hardik Makwana is a document available to read on EtoBox.

This document compares the constant strain triangle (CST) and linear strain triangle (LST) finite elements. The CST has 3 nodes and 6 degrees of freedom per element, while the LST has 6 nodes and 12 degrees of freedom. Displacement interpolation is constant for the CST but linear for the LST. Strains within each element are constant for the CST but can be linear functions of position for the LST. The stiffness matrix for the LST requires numerical integration since its terms depend on position, unlike the C
