| Abstract: | SHPB method with passive confined pressure was used to study the dynamic mechanical behavior of powder metallurgy friction material under quasi-one dimensional strain state,the dynamical poisson ratio,dynamical young's modulus and dynamical compressive yield strength were obtained. The friction force between the specimen and jacket under passive confined pressure were further analyzed. |
| Keywords: | powder metallurgy quasi-one dimensional strain dynamic mechanical properties SHPB |
