Test results show that for the stress-strain curves with no obvious peak strain, it is a available to use work hardening rate method to determine peak strain and stable strain.
The deformation and stress condition of the micro-composite are studied according to the shear-lag theory and strain-hardening law.
按照剪切滞后理论和应变硬化规律，研究微复合材料的变形和应力状态。
3
The elastic range, the plastic range (during which the material flows at a constant stress), the strain-hardening range, and the range during which necking occurs, terminating in fracture.
