Hi Pravin,
If I correctly understand what you want to do, you need to have a license for the Geomechanics Module, see www.comsol.com/blogs/yield-surfaces-plastic-flow-rules-geomechanics/.
You can check on which modules are included in your license via File>Used and Licensed Products.
Best regards,
Jeff
