Webis returned to the global stiffness matrix Kso that the matrix Kcontains the accumulated data from all elements. The global stiffness matrix Kin (P.4) is singular because there is a rigid body motion in the system. In order to remove the rigid body motion, the boundary condition must be applied. The displacement boundary condition is specified by Webyields the following mass matrix in the local element configuration: (6) For an element that remains straight, i.e., a truss element, the shape functions associated with the first and …
