Hello all,
I need to extract the element stress from SPRING2. Please check the attachment explaining the problem and input file.
Abaqus provides S11 values for SPRING2 elements. It will be very helpful to get it from Calculix too.
Thank you,
With Best Regards,
U Arun
What Abaqus provides as S11 for spring elements is just the force in the spring since these elements don’t represent any particular geometry and only model the behavior of springs.
@arun_udayakumar Like @Calc_em mentioned, these elements do not have a geometry associated with them. You need to request forces or displacements at these nodes if that is what you want to get. The documentation is pretty good:
Thank you Calc_em and jbr for your valuable inputs.
Which input deck cards can be used to print the SPRING2 forces in the model ?
Thank you,
With Best Regards,
U Arun
I’m afraid that, unlike Abaqus, CalculiX doesn’t offer any output variables for that. You can only request reaction force at the fixed end of a spring. For example:
*Node
1,0,0,0
2,10,0,0
*Element, type=SPRING2, elset=spring
1,1,2
*Nset, nset=fixed
1
*Nset, nset=loaded
2
*Spring, elset=spring
1,1
0.8
*Step
*Static
*Boundary
1,1,3
2,2,3
*Cload
2,1,300
*El print, elset=spring
S
*Node print, nset=fixed
RF
*Node print, nset=loaded
U
*End step
