Review the difference between small displacement linear, and large displacement nonlinear analyses. Introduce the concept of time curves, and discuss basic options. Solve small displacement linear analysis to demonstrate inaccurate solution. Define a nonlinear simulation study. Use time curves to control variation of the nonlinear loading. Use fixed increment stepping, and autostepping stepping procedures to solve the nonlinear problem. Postprocess results of the nonlinear simulation. Compare results from nonlinear studies with various setup parameters.
