摘要

对采用不同方法确定法向和切向应力强度的热粘塑性体模型建立了本构关系。根据不同温度下材料在拉压和扭转作用下的硬化实验图，确定了材料的参数。在该模型框架内解决了St3钢平行六面体两平行板间剪切沉降的模型问题。与基于单曲线模型的溶液比较，结果表明，两种溶液的定量差异不超过7%。

The Influence of Deformation Anisotropy on the Stress State of Metals During Plastic Deformation

The constitutive relations are constructed for the model of a thermoviscoplastic body with the normal and tangential stress intensities determined by different methods. The parameters of materials are determined on the basis of experimental diagrams for material hardening at different temperatures under tension-compression and torsion, respectively. The model problem of subsidence with shear between two parallel plates of a parallelepiped made of the St3 steel is solved within the framework of proposed model. A comparison with the solution based on the single curve model showed that the quantitative difference between the solutions does not exceed 7%.

期刊介绍： Mechanics of Solids publishes articles in the general areas of dynamics of particles and rigid bodies and the mechanics of deformable solids. The journal has a goal of being a comprehensive record of up-to-the-minute research results. The journal coverage is vibration of discrete and continuous systems; stability and optimization of mechanical systems; automatic control theory; dynamics of multiple body systems; elasticity, viscoelasticity and plasticity; mechanics of composite materials; theory of structures and structural stability; wave propagation and impact of solids; fracture mechanics; micromechanics of solids; mechanics of granular and geological materials; structure-fluid interaction; mechanical behavior of materials; gyroscopes and navigation systems; and nanomechanics. Most of the articles in the journal are theoretical and analytical. They present a blend of basic mechanics theory with analysis of contemporary technological problems.
