Linear Elastic Transient - GCMLab/GCMLab-FEM GitHub Wiki

The fully discretized weak form for the elastic transient case is the following,

where, is the damping matrix, is the stiffness matrix, is external force vector, is the time-step and is the time-step parameter.

C is defined as follows, where is the damping coefficient of the element.
