Mechanical Stress - an overview ScienceDirect Topics
WebTheoretical Mechanics in Earth and Environmental Science -- earthquake source processes, fault and crack dynamics, lithospheric stressing and seismicity, hydrologic and surficial processes, pore fluid interaction with … In continuum mechanics, stress is a physical quantity that describes the magnitude of forces that cause deformation. Stress is defined as force per unit area. When an object is pulled apart by a force it will cause elongation which is also known as deformation, like the stretching of an elastic band, it is called … See more Humans have known about stress inside materials since ancient times. Until the 17th century, this understanding was largely intuitive and empirical, though this did not prevent the development of relatively advanced … See more Stress in a material body may be due to multiple physical causes, including external influences and internal physical processes. Some of these agents (like gravity, changes in See more Often, mechanical bodies experience more than one type of stress at the same time; this is called combined stress. In normal and shear stress, the … See more Stress is defined as the force across a small boundary per unit area of that boundary, for all orientations of the boundary. Derived from a fundamental physical quantity … See more The dimension of stress is that of pressure, and therefore its coordinates are measured in the same units as pressure: namely, pascals (Pa, that is, newtons per square metre) … See more In some situations, the stress within a body may adequately be described by a single number, or by a single vector (a number and a direction). Three such simple stress … See more Combined stresses cannot be described by a single vector. Even if the material is stressed in the same way throughout the volume of the body, … See more Webresenting the volumetric stress or the hydrostatic pressure in the incompressible limit. σis the Cauchy stress tensor, εI is the inelastic or the plastic strain ten-sor, and K is the bulk … iowa farm rental rates
