Abstract
Finite element methods for dynamic analysis employing elements with dr illing degrees of freedom are presented. The formulation is based an a variational principle in which displacements and rotations are interp olated independently. The issue of zero masses corresponding to rotati onal degrees of freedom is addressed and techniques for defining consi stent and lumped rotational mass matrices are presented.
