PW-1

Workshop Objectives Learn the typical workflow of a finite element analysis using

Patran and MD Nastran. Perform a start to finish finite element analysis of a solid model.


PW-2

Problem Description A landing gear strut has been designed for a new fighter jet.

Determine if the landing gear strut has been designed properly to withstand the landing load.

E = 30 x 106 psi =0.3 Landing Load = 7,080 lb


PW-3

Suggested Exercise Steps1. Create a new database and name it strut.db 2. Import the strut geometry strut.xmt 3. Mesh the strut to create solid elements with global edge length = 0.5

PW-5

Suggested Exercise Steps4. Fix the cylindrical hole at the bottom of the strut 5. Apply a total load of 7080 lb in the negative Y direction to the circular surface at the top of the strut


PW-6



PW-7

Suggested Exercise Steps6. Create an isotropic material with elastic modulus = 30e6 and Poisson's ratio = 0.3 7. Create a physical property, applying your isotropic material to the entire solid
