Document Summary

For critical things, fs of 4 or greater is used. In aerospace, over-engineering has a very high cost, so fs can be as low as 1. 2. Right-click results folder >> define factor of safety plot. Von mises and tresca are used for ductile material. So meeting fs in tresca will result in over-engineered design. Von mises works just fine for linear material. Yield strength can be selected as the stress limit. Areas below fs and enter target fs value. Box at bottom shows min fs that design can support. Anything in red is below your target fs. anything in blue is above. Solid mesh is appropriate for bulky things without thin features. Ex, parts that are machined or forged. Thin walled modeled such as sheet metal parts and surface models. Right click on fixture >> fixture geometry. Standard mesh creates even mesh throughout the part. Automatic transitions improves the quality of your mesh.
