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.
弹性范围，塑料范围（当材料以不变的应力流动时），应变硬化范围和发生颈缩现象以其断裂终止的范围。

Thermal stress in meteoroids by aerodynamic heating is calculated for the ideal case of an isotropic, homogeneous, elastic sphere being heated at the surface with a constant heat transfer coefficient.
Several linear polyene compounds with extraordinarily large dielectric anisotropy and small elasticconstant were synthesized and their physical properties evaluated.
