1. ## linear static with contacts

@Prakash Pagadala Lets take a simple example for explanations sake. If a plate is pushed onto another plate (such that the two plates are in contact). How can i find the force transferred at the contact regions?
2. ## linear static with contacts

@Prakash Pagadala I am carrying out a fixed displacement analysis. The reaction force on the bottom plate should be equal and opposite to the contact force experienced by the plate. But when i obtain the nodal reactions and nodal contact forces they are not balancing each other
3. ## linear static with contacts

@Prakash Pagadala While carrying out the non linear analysis I am unable to obtain a force balance (between contact force and reaction force) on the plates. I tried defining different conditions of contact (slide and stick) however in both the cases i am unable to obtain a force balance. Something seems to be wrong. I can transfer the file if needed.
4. ## linear static with contacts

Thanks for your reply. I have now carried out non linear analysis and now the results make sense.
5. ## linear static with contacts

still havent figured it out. can anybody help?
6. ## linear static with contacts

@Prakash Pagadala I have shared the model files with you.
7. ## linear static with contacts

I am carrying out a linear static loading of helical spring, which is interfaced between two plates and have defined slide contact between the spring and the plates. Upon applying the load to the top plate i obtained the spcf forces on the bottom plate nodes. However, I am obtaining unexpectedly high loads at the contacts (100 times higher than the loading force~1000). Am i doing something wrong in setting up the contacts? I am attaching pictures of result, setup and contact surfaces for clarity
8. ## design of experiments by changing parameters of geometry

Hi, I want to carry out a static structural study on a helical spring such that i have the freedom to change different parameters of the geometry (about 5 parameters in total) using a a script ( and a means to avoid manual meshing). Is there any means to carry out such a study using Hypermesh?
