Habituating FEA

Shape functions are polynomial functions that interpolate the discrete displacements into continuous functions. They are therefore also know...

During the assembly of the global stiffness matrix (K) , local stiffnesses are numerically integrated in the parent coordinate (the polyno...

Gaussian quadrature is a method that replaces an integral by a sum. As an example, consider the following 1D integral: Gaussian quadratu...
