Description
Photo elasticity is a proven method of analyzing and recording mechanical stresses and strains in components. It is used both for quantitative measurements and for demonstrating complex stress states. The components used are models made of a transparent, photo elastically sensitive plastic, which becomes optically birefringent under mechanical load
Specification
- produce the mechanical stress curves through photo elastic experiments
- 2 linear polarizing filters (polarizer and analyzer)
- 2 quarter-wave filters for generating circular polarized light
- all filters have 360° angle scale and indicate the main optical axis
- filters mounted on roller bearings and can be pivoted
- white light produced by a fluorescent tube and two incandescent bulbs
- monochromatic light (yellow) generated by sodium vapor lamp
- frame cross-members can be vertically adjusted
- pressure or tensile forces generated by a threaded spindle
- finished polycarbonate (PC) models available as accessories for the demonstration
