Photoelastic Experiments With A Transmission Polariscope

Product Description

Photoelastic Experiments With A Transmission Polariscope

Photoelasticity is a proven method of analysing 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, photoelastically sensitive plastic, which becomes optically birefringent under mechanical load.  

Learning Objectives And Experiments

1. Together with the accessories or your own models:
2. Generate plane stress states in various models under load: bending, tensile load and compressive load
3. Investigate stress distributions with linear or circular polarised light
4. Interpret photoelastic fringe patterns: stress concentrations, zero points, neutral strands, areas of constant stress and stress gradients
5. Graphically and computationally determine the stresses

Features

1. Monochromatic or white light
2. Generate stress patterns with linear or circular polarised light
