Finite Elements
Two important aspects of the finite element method are summarized in this chapter. Starting with the derivation of the principle of virtual work (displacement), a general expression for the element stiffness matrix is derived. In the second part, details of the formulation of the most commonly used element (isoparametric) are presented.
Though understanding of this chapter is not critical for the practitioner, it does nevertheless hint to practical issues that they may be confronted with (such as element distortion, nodal equivalent loads, stress recovery, or convergence) as the practicing engineer.
