Hi FEA way,
I can not thank you enough for your help!! Your method allowed only internal part to deform as it should! However, unreasonably high stress is observed in internal part even though its a free object where no stress should be formed due to thermal expansion or contraction.
Would you...
Yes, of course!
I had to quickly remake the example. Strangely, the result is slightly different because the inner part shrunk as it should instead of outer part (which was happening constantly). However, unreasonably high stress is observed even though they are free surface where the stress...
It seems like there is an error when sequencial thermo-mechanical analysis performed using shell model in Abaqus.
As shown in the pic below, the outer part that has no temperature change thus should show no displacement shows large displacement and extremely high stress.
Perhaps there is an...
Oh I see!! I gave it a try using 298K as a reference temperature but still no luck. However, I was able to get fairely reasonable result using coupled thermo-mechanical analysis with the same conditions.
I am using 1.15E-005 as thermal coefficient of stainless steel. I believe all the material...
Hi FEA way,
Thanks for such prompt reply! I used predefined field to give initial reference temperature of 298K. My model is two parts: internal and outer part. Internal part has temperature of 50K (given by BC) and outer part is at 298K. The result from post-thermal static analysis show...
Hi, I am getting a weird result where the part that has no temperature change is shrinking (drop in temperature).
The result from thermal analysis was spot on, but when the result was applied (ODB file to predefined field) to the static analysis the expansion of my part simply doesn't make...
