To extend the principle of virtual work for dynamic systems, mass accelerations are introduced.
Then the principle of virtual work is written on each of these elements with a local finite element approximation and evaluated to yield element discrete equations which are then assembled so as to form an approximate membrane representation [11].
The elastic solid approach employs either continuum mechanics (5, 6) or the principle of virtual work (7-12) in the formulation.
The present finite element formulation (11, 15) is based on the principle of virtual work. The thin shell approximation, which neglects any bending, twisting, and transverse resistance in the thickness direction, is used.
