Simply supported beam modeled with two dimensional solid elements

Example Provided by: Vesna Terzic, UC Berkeley

---

This example (adopted from the old OpenSees Examples Manual) considers a simple problem in solid dynamics. The structure is a simply supported beam modelled with two dimensional solid elements (quadrilateral elements). The beam is first exposed to static load (two nodal loads) and then to free vibrations caused by removal of the static load. Fig. 1 shows the geometry of the beam and the static load. Units adopted for this example are: kip, inch, sec. Fig. 2 shows the global coordinate system, finite element mesh, and nodal numeration.
