船用907 A钢的动态力学性能和本构关系
Dynamic mechanical behavior and constitutive relation of the ship-built steel 907A
摘要
Abstract
In order to get the dynamic mechanical properties and constitutive relation of the ship⁃built steel 907A, the stress⁃strain curve within the scope of 0.000 33~2 680 s⁃1under quasi static stretching and dynamic compression condition was derived using the static testing machine and split Hopkinson press bar ( SHPB) . The Johnson⁃Cook ( JC) model and Cowper⁃Symonds ( CS ) model were compared and the hardening effect of strain was corrected based on the CS model. The results showed that ship⁃built steel 907A has a remarkable effect in strengthening strain rate and hardening nonlinear strain, and the CS model can describe the effect of strengthening strain more exactly than JC model.关键词
