If all materials are defined materials, you can forego material overrides. In the Assign Materials dialog box, expand the browser material nodes to view component material assignments at the Part model level, and component material overrides.The Steel node contains nodes for each part using that material. For example, if you have a Copper component, and override the Copper with Steel, there is a unique node for Steel. In the browser, double-click the parent Material node, or right-click the node and select Assign Materials.Īll materials that override other materials are listed. On the Stress Analysis tab Material panel, click Assign.

UTS = Ultimate Tensile Strength (as in the material properties)įor the max principal stress, we compare the σ 1 and σ 3 values to account for special combinations of tension, bending, torsion, or shear: The setting affects the component material for that simulation. Safety Factor specifies whether to use Yield Strength or Ultimate Tensile Strength. (Less than 1 means there is some permanent deformation.) When using Ultimate Strength, Maximum Principal stress is used to determine safety factor ratios. It must be over 1 for the design to be acceptable. You can calculate a factor of safety as the ratio of the maximum allowable stress to the equivalent stress (von-Mises), when using Yield Strength. If a design is not supposed to deform permanently by going beyond yield (most cases), then the maximum allowable stress in this case is 40,000 psi.

If steel has a yield limit of 40,000 psi, any stresses above this limit result in some form of permanent deformation. All objects have a stress limit depending on the material used, which are presented as material yield or ultimate strengths.
