This chapter explains the method of weighted residuals and the Rayleigh–Ritz method, thereby providing a basis for the finite-element method (FEM). Differential equations are generally formulated to be satisfied at any points, which belong to regions of interest. When the functional that is ...
The finite element method describes a complicated geometry as a collection of subdomains by generating a mesh on the geometry. For example, you can approximate the computational domain Ω with a union of triangles (2-D geometry) or tetrahedra (3-D geometry). The subdomains form a mesh, and ...
The use of finite element analyses (FEA) is widespread in pipeline engineering practice, in particular for major hazard industries such as oil and gas. It allows a comprehensive understanding of the loadings and resistances at each specific region, and a
These finite number of basis functions (blending functions or interpolants) are the fundamental objects of the finite element method. The resulting nodal forces and displacements yield symmetric (positive semi-definite) system matrices.The "energy minimization" concept is introduced using a single ...
not be possible to give a comprehensive introduction on this subject in a single chapter, we do wish to highlight some of the most important analytical methods: separation of the variables and integral transforms, as well as numerical methods, the difference method and finite element method. We...
