Equipment for bulge testing metal foils using a laser scanner

621

bulge testingA fast, cost effective and simple methodology and testing apparatus was developed for testing basic material properties of thin (up to 0.05 mm) metal sheets during production. The method is based on the bulge test method. Air is used as a pressurizing medium and specimen deformations are measured using a 2D laser scanner. Test control and software for evaluating results was programmed in MATLAB using the GUI feature. The testing procedure and test assembly were developed with the accent on simplicity and obtaining fast results, which are both necessary for fast product testing during the manufacturing process.
