Well, put simply, it is a device that can show you the photoelasticity of a clear specimen, which can reveal the stress distribution in the material! And it is actually really easy to make one.

To get that 3D view, they use a combination of the photoelasticity to illuminate the force chains, along with a method called computed tomography, similar to that used in medical CT scans, to ...

4) have also been investigated by photoelasticity. The deformation and contact area for a ball in a race were measured by Whittemore and Petrenko (Ref. 8) and compared with the theoretical values.

Photoelasticity). Structural Analysis: To determine Stress-strain curves of a tested component; To identify its yielding point; To determine its plastic failure point. To work safely and conduct ...

The basic research developments include original mechanical models, dedicated laboratory and field experimental apparatuses and ideal testing systems utilizing photoelasticity, image acquisition and ...
