Access to Material Properties

The property panel for a material can be activated by selecting the title of the target material in the Object Navigator as shown in figure above. Various properties are supported to change the material such as finish, treatment, and parameters for SN/EN curves, as shown in the figure and table below.

Category Content Description
MiscNameUsed to set the name of the material property.
GeneralData TypeUsed to set the material property type. You can select either SN or EN, which determines how to evaluate the fatigue life. See fatigue life evaluation.
Pressure UnitUsed to set the unit for pressure values.
Finish TypeUsed to show the finish type. Only User Defined is available. Surface finish is the surface roughness and waviness which are determined by manufacturing processes such as cutting, abrasion, casting, and forming.
Finish Value

Used to set the value for the finish. This value is generally smaller than 1, and will decrease the fatigue strength as shown in the figure below.

Material Properties

Treatment TypeUsed to show the treatment type. Only User Defined is available. Surface treatment controls the residual stress of the surface after surface finishing. Examples include mechanical treatments such as shot peening, cold rolling, thermal treatment of carbon and nitrogen, and plating processes.
Treatment Value

Used to set the value for treatment. This value is generally greater than 1, and will increase the fatigue strength as shown in the figure below.

Material Properties
