Webb• Same shapppe functions are used to interpolate nodal coordinates and displacements • Shape functions are defined for an idealized mapped elt( f diltll t)lement (e.g. square for any quadrilateral element) • Advantages include more flexible shapes and compatibility • We pay the price in complexity and require numerical WebbThe most straightforward interpretation of the finite element method is to consider it as a method for integration of functions on complex shapes. The integration domain is divided into elements with primitive shapes, e.g. edge, triangle, quad, tetrahedron, or hexahedron, and on each element integration rule for the primitive shape is evaluated.
