This tutorial demonstrates a simple linear buckling analysis of a dome lid model.
- The goal of this eigenvalue extraction analysis is to determine the lowest critical linear buckling load from the eigenvalues extracted.
- Typically, in a linear buckling analysis, a unit load is applied. Inventor Nastran then calculates an eigenvalue that, when multiplied by the applied load, gives the critical buckling load. In this case, you will use a unit pressure load.
- The dome lid is made of aluminum alloy.
- The units used in this analysis are inches, pounds, and seconds. The effects of gravity are not considered in this model.
