28. Introduction to Constant Strain Triangle (CST) element

The linear triangular element or constant strain triangle element (CST) was the first type of element developed for finite element analysis of 2-D structure. Although it is less accurate, it is still a useful element for its adoptivity to complex geometry. CST is the simplest element to develop mathematically. In this video, I have introduced CST element, and have discussed various 2-D cases.
