I want to solve one multi degree freedom system in which the stiffness matrix is nonlinear .My system is 12 x 12 in which for every displacement value , the stiffness matrix is changing .
It will be great if i can support. If you guys have any documents please share with me.
Thanks and Regards
Ram

Hi Ram,
You can refer to the following File Exchange submission to have a look at the implementation of Newmark-Beta method for Nonlinear Single DOF Systems to get started :
Additionally, the code snippet provided in the answer of the following MATLAB answer might nudge you in the correct direction for implementing it for multi DOF systems:
Hope this helps!
Best,
Umang
