is it possible to get "yield stress at ambient temperature" AS the "von misses stress at very high temperature"?

 

 

 I didn't do any thermal analysis but only doing structural analysis but i am using measured temperature values to my structural model. I created temperature loading with time (Using amplitude method as you mentioned). Plastic perfect material model created with respect with temperature.

 

I used Nonlinear Static Analysis with Linear Perfect plastic materialmodel. (fy=612 at Temperature=20°C)

The yield stress and elastic modulus values wereinput with respect to temperature (Using FIELD)

Abaqus modelling to find out the time of failure when increasing the temperature???

Hi all,

 

If you can pls advise me to modelthis experiment.

 

First I have applied a constantload for the steel member.

Then I have increased thetemperature of one of the member surface with time

until the member got failed.

This resulted in non-uniformtemperature variation across the section.

I have measured the temperaturesof the different surfaces of the member and

I would like to use thesetemperature values in my structural modelling.

Now I would like to model themember so that I can find out the time
