Hello
Non-linear effects, such as a spring failure load, can not be calculated with an elastic boundary element. You have to use multiple springs with non-linear stress-strain curves or a material with a tensile stress maximum.
Please have a look at the following commands. They will help you understand the workflow.
- BMAT CRAC… (AQUA)
- SPRI CRAC … (SOFiMSHA)
- SPTS CRAC … (SOFiMSHC)
Keep in mind that non-linear effects are not considered within a linear analysis. You have to run a non-linear calculation with ase.
I would advise you to test the program behaviour with SOFiPLUS(-X) / the SSD and export the relevant tasks to .dat. I have created a short example for you that demonstrates a possible workflow.
