| 摘 要： | In order to characterize the plastic state of a deformed material,an indentation method to determine the plastic equation of state (PES) was developed.The work-hardening coefficient and the strain rate sensitivity coefficient of the plastic mechanic equation of state were determined by two kinds of indentation tests respectively.Therefore,the PES of materials under deformation can be obtained,and the plastic state of materials can be determined.
