Transient loading of an L-beam

Home » Knowledge » Implicit » Guideline Examples » Transient loading of an L-beam

An L-shaped beam is loaded by a transverse, transient (triangular) loading, see Figure 23. A constant modal damping of 3 % is applied. The transient displacement response of the loaded node is shown in Figure 24. The example keyword file is transient001.key.
