FINITE ELEMENT ANALYSIS What are the different types of boundary conditions in finite element analysis? Provide examples of each. Define the finite element method (FEM). How is it applied in solving engineering problems? What is a node or joint in the context of finite element analysis? Explain its role in the formation of the element matrix. Write the general finite element equation used to solve problems in structural analysis. Explain the concept of global coordinates in finite element analysis. What are CST and LST elements in finite element modeling? How do they differ? Write the stiffness matrix equation for a two-dimensional CST element in finite element analysis. What is meant by discretization in the finite element method? Provide an example of its application. Using the direct stiffness matrix approach, determine the stiffness matrix for: (a) A bar element, (b) A truss element Write a short note on Galerkin's method. Explain its significance in finite element analysis.
