What is 2D Finite Element Analysis Basics about?

The document summarizes finite element analysis for 2D plane problems. It discusses: 1) 2D plane problems are simplifications of 3D problems by assuming stress/strain components in one direction are zero, known as plane stress or plane strain. 2) Linear triangular elements are described for interpolation of displacement over three nodes. Shape functions are derived. 3) Strain is defined at each element in terms of the displacement derivatives and shape functions. Stress is related to strain through const
