The GUNT Photoelastic Experiments with a Transmission Polariscope trainer is designed for analyzing and visualizing mechanical stresses and strains in transparent plastic models using photoelasticity. This proven method enables both quantitative measurements and demonstrations of complex stress states under various loading conditions.
Product Features
- Conducts photoelastic experiments on plane, transparent plastic models sensitive to mechanical load.
- Models become optically birefringent under load, allowing visualization of stress distribution.
- Experimental setup includes a light source, two linear polarising filters (polariser and analyser), two quarter-wave filters, and a frame for mounting and loading models.
- Light source supports coloured stress patterns with white light or light/dark representation with monochromatic light.
- Polariser combines a polarising filter and quarter-wave plate to generate circular polarised light.
- Analyser consists of a second quarter-wave plate perpendicular to the first and a second polarising filter; both mounted on rotating bearings with angle scales.
- Models are mounted inside the frame and subjected to bending, tensile, or compressive loads via a spindle-operated load device.
- Stress and strain appear as bright spots, visualizing stress distribution; dark isochromats order analyzed to determine principal stress differential.
- Includes a selection of polycarbonate models such as notched bars, a wrench, a model-roller bearing, and a rack-and-pinion as accessories.
- Allows investigation of custom models for comprehensive experiments.
- All components are securely housed in a well-organized storage system.
Benefits
