Different types of stresses in materials
Another simple type of stress occurs when the material body is under equal compression or tension in all directions. This is the case, for example, in a portion of liquid or gas at rest, whether enclosed in some container or as part of a larger mass of fluid; or inside a cube of elastic material that is being pressed or … See more 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 … 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 Humans have known about stress inside materials since ancient times. Until the 17th century, this understanding was largely intuitive and … 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 (force) and a purely geometrical quantity (area), stress is also a fundamental … 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 … See more WebMay 19, 2006 · Forces may be applied in different directions such as: • Tensile or stretching. • Compressive or squashing/crushing. • Shear or tearing/cutting. • Torsional or twisting. This gives rise to numerous corresponding types of stresses and hence …
