文摘
- •
A stress–strain curve of hardened steel material is obtained with SHPB technology.
- •
A negative strain rate effect and temperature effect are considered.
- •
The conventional empirical Johnson–Cook constitutive equation is thus modified.
- •
A 2D finite element model for high-speed milling predicts chip formation.
- •
Stress–strain is obtained in the shear band during continuous chip transformation.
