Photoelasticity | Stress Analysis, Stress Measurement & Stress ...
网页Photoelasticity, the property of some transparent materials, such as glass or plastic, while under stress, to become doubly refracting (i.e., a ray of light will split into two rays at entry). When photoelastic materials are subjected to pressure, internal strains develop that can be observed in.

Photoelasticity
网页Photoelasticity. Many transparent noncrystalline materials that are optically isotropic when free of stress become optically anisotropic and display characteristics similar to crystals when they are stressed. This behavior is known as …
Photoelasticity - an overview | ScienceDirect Topics
网页Photoelasticity is a technique used in stress analysis testing based on the ability of a transparent non-crystalline material that is isotropic when free of stress to become optically anisotropic displaying stress characteristics when stressed.
Introduction to Photoelasticity - SpringerLink
网页2015年1月1日 · Photoelasticity allows the complete knowledge of the values and signs of Shear stresses and of the normal stresses difference at any point of a model, since these data derive from the knowledge of isochromatics and isoclines.

网页Photoelasticity, being a strain-induced phenomenon, is exploited in reflection photoelasticity to study prototypes made of different materials, in orthotropic photoelasticity to study composites, and in photoplasticity to study strains beyond elastic limit.

网页2021年11月16日 · Photoelasticity is a simple full-field optical method of experimental mechanics. Its name comes from the Greek words “photo” which means light and “elasticity” which refers to the ability of an object or material to resume its normal shape after being stretched or compressed.
Photoelasticity is a full-field technique used in stress analysis ...
网页Photoelasticity is a full-field technique used in stress analysis testing. When a photoelastic material is subjected to load and viewed with polarized light, colorful patterns are seen which are directly proportional to the stresses and strains in the material.

网页One of the oldest and most useful forms of interferometric measurement for engineering purposes is photoelasticity, which involves the observation of fringe patterns for determination of stress-induced birefringence. It is important as a measurement technique.

网页2019年5月17日 · Photoelasticity is the property of some transparent solid materials, such as glass, crystals, or plastic, to become doubly refracting under the influence of external stress.
网页Photoelasticity is a nondestructive, whole-field, graphic stress-analysis technique based on an opto- mechanical property called birefringence, possessed by many transparent polymers.
