I need to do a stress analyze of a hook feature in a plastic material in SI units.
But I don't have the material properties file for my material: Sabic Cycoloy C2100HF.
I do have a full datasheet for the material, but some of the properties are not mentioned.
Which are minimum properties to be in a material file do do a stress analyze?
YOUNG_MODULUS =
POISSON_RATIO =
SHEAR_MODULUS =
MASS_DENSITY =
THERMAL_EXPANSION_COEFFICIENT =
THERM_EXPANSION_REF_TEMPERATURE =
STRUCTURAL_DAMPING_COEFFICIENT =
STRESS_LIMIT_FOR_TENSION =
STRESS_LIMIT_FOR_COMPRESSION =
STRESS_LIMIT_FOR_SHEAR =
THERMAL_CONDUCTIVITY =
EMISSIVITY =
SPECIFIC_HEAT =
HARDNESS =
CONDITION =
INITIAL_BEND_Y_FACTOR =
BEND_TABLE =
PRO_UNIT_MASS =
PRO_UNIT_LENGTH =
Plastics typically don't specify Young's mod. Flexural mod and tensile mod are usually provided. I've used flex mod in the past with good success and I worked with Cycoloy (or PC-ABS equivalents) a lot (it's good stuff). I'd input flex mod for Young's and .3 for poisson's unless you can find that. That's all you should need to run.
Hello, Erik,
You should find some additional information on these two links.
Cordially.
