NAS103: MSC/NASTRAN Nonlinear Analysis
Spring Element with Nonlinear Analysis Parameters (large displacements on): Demonstrate the effects of geometric nonlinear analysis and how to interpret the results.
Spring Element with Nonlinear Analysis Parameters (Multi-Step Analysis): Demonstrate the effects of geometric nonlinear analysis with incremental loads through multiple subcases and interpret the results with different output options.
Spring Element with Nonlinear Analysis Parameters (Restart a Multi-Step Analysis): Use the Restart feature on the previous exercise to introduce an intermediate load case and use data obtained from the first part of previous analysis.
Spring Element with Nonlinear Analysis Parameters (filter using restart): Use another feature of Restart to introduce multi step analysis by keeping only the first part of the analysis as a separate result file.
Linear Buckling Load Analysis (with spring): Demonstrate the use of nonlinear static analysis restarted with buckling parameters.
Nonlinear Snap-ThroughBuckling Load Analysis (different spring constants): Demonstrate the use of nonlinear static analysis for a snap-through load and show the effects of different spring constants on the load-deflection curve.
