基于应力张量的三个不变量和某些常数，建立了非线性变形的本构方程和强度准则。导出了特殊的物理关系，并提出了一种确定常数的方法。将计算结果与复杂应力状态下的实验数据进行了比较。给出了用拉压性能不同的材料设计矿用管道时，用数值方法解决边缘问题的表述和方法。建立了强度差异程度对管道应力-应变状态和强度的影响。
Constitutive equations of nonlinear deformation and a strength criterion are proposed on the basis of three invariants of the stress tensor and certain constants. Special physical relationships are derived, and a method of determining the constants is addressed. The results of the computations are compared with experimental data for a complex stressed state. The statement and method used to solve edge problems numerically in designing mine pipes formed from materials that behave differently in tension and compression are given. The effect of the extent to which the strengths differ on the stress-strain state and strength of the pipes is established.
