High performance graphene pressure sensor is adopted to measure the in-situ stress. The COMSOL software is used to simulate and analyze on graphene membrane under high-stress

and the simulation results are compared with results calculated by different theories to verify the reliability of COMSOL simulation results without considering the destruction of graphene membrane. Then the deformation and mechanical properties of single and multi layers of graphene membrane under high-stress are analyzed by COMSOL software

and discuss whether graphene membrane is failed

and simulation and theoretical results are compared in unbroken stage to verify the reliability of the simulation analysis of graphene membrane. By researching on validity of graphene membrane under high stress conditions

it provides a new method for measuring deep high in-situ stress.
