Photoelastic Stress Analysis Setup
Approx. component budget: Rs. 5,000 - 9,000
Objective
Visualise stress concentration around holes and notches and compare the fringe patterns with theory.
What you will build
A polariscope with a light source and polarising sheets, a small loading frame, and models cut from clear acrylic sheet with holes, notches and fillets.
Results you can expect
- Fringe pictures for different shapes
- Stress concentration factors
- Effect of fillet radius
- Comparison with FEA
What you will learn
Stress concentration, photoelasticity, and how design details change strength.
Tools and notes
Polarising film, camera, CAD/FEA software, Excel. Cut acrylic carefully and load it gradually.
Resume points from this project
- Built and tested Photoelastic Stress Analysis Setup; objective: visualise stress concentration around holes and notches and compare the fringe patterns with theory.
- Measured and analysed fringe pictures for different shapes and stress concentration factors; wrote the report and presented the results in a viva. Add your own numbers: [x].
Replace [x] with your own measured results. Write only what you really did.
