Stress analysis is a crucial step for a design or strength analysis. The methods of experimental analysis are indispensable for validation when the approximations in the analytical and numerical methods are taken into account. As one of the first experimental methods, photoelasticity
offers a very useful way to analyze different models of transparent material. Not only two-dimensional stress analyses are performed with this method, but also a full three-dimensional analysis can be
performed with the strain-freezing method based on the viscoelastic property of the material used. In the Experimental Mechanics Laboratory at Istanbul Technical University (ITU), various models from different research areas are produced and analyzed, from civil engineering to biomechanics or
mechanical engineering to dental technology. This presentation summarizes some of the interesting experiments carried out in this laboratory.
