Stress analyze

Stress analyze

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 =

Re: Stress analyze

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.

Re: Stress analyze

Hello, Erik,

You should find some additional information on these two links.

Cordially.
