Example: Specifying Material Parameters through Relations
You can use material parameter values in relations.
For example, in a part:
• Assign a value to the parameter HARDNESS in the material with MTRL_ID 64. The material must be in the internal database of the part (but is not necessarily assigned to the part):
PTC_HARDNESS:MTRL_64 = 55
• Assign a value to the parameter POISSON_RATIO in the assigned material:
PTC_POISSON_RATIO:MTRL_ID = 0.3
(where MTRL_ID is ID of the assigned material)
• Make a dimension dependent on the material parameter YOUNG_MODULUS:
d12 = PTC_YOUNG_MODULUS:MTRL_ID/1000
For example, in an assembly:
• Assign a value to the material parameter POISSON_RATIO in the component with Session ID 10:
PTC_POISSION_RATIO:MTRL_ID:10 = 0.30
• Make dimension d17 dependent on the material parameter HARDNESS in the component with session ID 21:
d17 = PTC_HARDNESS:MTRL_ID:21 * 40
If a material parameter is used as driving variable and you change it, the driven variable or dimension, likewise, is updated after regeneration.
