变形、流动和断裂力学

To mechanics of deformation, flow, and fracture

S. L. Arsenjev

摘要:

从统计各向同性材料和均质流体动力学出发,主要阐述了固体应力状态力学的新途径。其实质是在自然状态下和在外力作用下,固体和液体的内能的核-壳自发结构化的检测性质。本文叙述了建立固体和液体的应力状态的物理上适当的模型的方法原理,该模型精确地再现了固体和液体在弹性和塑性形变、流动和断裂阶段的行为。列举了简支模板在拉、压、扭及接触相互作用下的受力状态施工实例。首次提出了圆柱杆在扭矩作用下的主正应力结构。与传统方法相比,所检测到的性质和所开发的方法是构造身体和流体的应力状态的物理上适当的数学模型的必要基础之一。

英文摘要:

It is stated in the main in essence new approach to mechanics of the stressed state of the solid body from statistically isotropic material and the homogeneous liquid dynamics. The approach essence is in the detected property of the core-shell spontaneous structurization of internal energy of the solid and liquid bodies in its natural state and under action of external forces. The method elements of construction of physically adequate model of the stressed state of the solid and liquid bodies, reproduced exactly its behavior on the stages of elastic and plastic deformation, flow and fracture, are stated. It is adduced a number of the examples of the stressed state construction of the simple form bodies under action of its tension, compression, torsion and at its contact interaction. For the first time it is adduced structure of the principal - normal - stresses in cylindrical bar under action of the torsion moment. The detected property and the developed method is one of necessary bases for construction of physically adequate mathematical model of the stressed state of the body and fluid in contrast to traditional approach.
