Specifying the temperature dependent material property for the Moldflow Analysis

[madhurahande]

Hi

For the moldflow(e.g Fill+pack) analysis which uses any plastic e.g PBT GF33% we choose the material property at the room temperature as E1, E2, v12, v23,G12 and Alpha1, Alpha 2 etc.  All these properties are room temperature properties. Is there a option to choose these properties or input these properties as a temperature dependent properties in the moldflow analysis software? 

Analogy would be in any simulation [ mechanical , thermal ] etc we define the properties as a temperature dependent. because for such plastic properties vary drastically with temperature.

I am asking this question because I am in the process of mapping the properties from the Moldflow Analysis to Structural Analysis using AMSA interface. It does properly the mapping but I wanted to get the temperature dependency in the properties as well which can only be possible if it can be defined as a temperature dependent property in the moldflow analysis.

Hi everyone,

I have the same problem. I would like to use material properties from AMI by use AMSA to Abaqus in thermal stress analysis. The problem is that the material properties from Moldflow are dedicated to temperature equal to 25 Celcius. Is it any way to obtain values of material property to other temperature or other method to perform correct thermal stress analysis?

I think that thermal expansion coefficient is not enough to evaluate correct maximum stresses because of changing Young modulus under the influence of temperature of used material.
