4.4 CLOSING REMARKS
In this chapter, different approaches and detailed analysis procedure in finite element methods are introduced. Procedures for applications of various FEM approaches are discussed in detail. After the problem domain is discretized in FEM, variables are approximated in each element using some relationships or trial functions to form element property matrix. Most commonly used FEM approaches for derivation of element property matrix are direct approach, variational approach, energy approach and method of weighted residual. As discussed in this chapter, each FEM approach has its own advantages and limitations. Depending upon the problem to be solved, suitable FEM approach can be chosen for the solution.
Use of direct approach ...
