Some conclusions of the explosive stress field at the end are discussed according to the optical law of the dynamic twodimensionalstress.
根据动态二维应力光性定律,得出了端部应力场分布的定性结论。
2
The model satisfies the twodimensionalstress equilibrium, Mohr's cricular strain compatibility and softened biaxial constitutive laws of concrete.
这种模型满足二维应力平衡条件、莫尔应变协调条件和混凝土双轴软化本构关系。
3
A distribution function of twodimensional threshold is given for fatigue crack propagation. A twodimensionalstress threshold interference model is set up.
