ST7-1.20.20.9 Using Static Initial Conditions in Dynamic Analysis
Static solutions can be used as initial conditions in dynamic analyses to model systems which are pre-loaded but initially at rest; this considers the effect of an initial state of displacement and/or stress on the dynamic response. We will analyse a simple cantilever beam which sags due to self-weight (nonlinear static solution) and is then suddenly loaded to produce a dynamic response (nonlinear transient dynamic solution).
We will first set up the dynamic model without static initial conditions...
