1·The combined deformation due to torsion and tension of incompressible rigid viscoplastic circular shafts is analyzed.
分析了不可压缩刚粘塑性圆轴扭转和拉伸的组合变形。
2·A new evolution equation of growth of spherical voids in viscoplastic medium un-der dynamic tensile loading is presented in this paper.
提出了一个新的粘塑性介质中球形孔洞在高加载率作用下的演化方程。
3·Because of the dominance of viscoplastic deformation in the creep process, creep curves under triaxial compression behave without the third phase of atypical creep curve, viz.
蠕变过程中粘塑性变形占主导，因而其三轴蠕变曲线没有出现渐进流动阶段。
4·Under the instantaneous strain and yield limit calculated, judgement rule about viscoelastic and viscoplastic is established.
