Hi everyone,
I have been trying to model a prestress bird strike on WB Ls Dyna. But i couldnt find how can i do that.
Firstly I have pressure and thermal loads on the model. Bird strikes to part while it is under the stress.
I saw some examples not detailly but static structural solution is connected to ls dyna setup. There is some point that i didnt get it, when i modeled the bird with SPH how can i constraint and include static solution?
Do you have any idea or example for me ?
thanks.
regards,
mrlazlo
@mr_lazlo : there are two methods to impart prestress in lsdyna :
1. Control dynamic relaxtion
2. Interface springback to get dynain.
It depends on which method you want to follow, and for further info please refer the following journal:
