Some Fracture Studies using Digital Photoelasticity.
Masters thesis, Indian Institute of Technology Hyderabad.
Abstract
The fracture analysis of cracks in a structure under complex loading is an important topic to study from safety and cost perspective. This can be studied in di erent ways like theoretical, numerical or experimental. Theoretical solutions are too ideal for solving the actual structure. For complex cases, numerical or experimental methods are best suited. Photoelasticity has evolved as the most
preferred techniques for the evaluation of fracture parameters. The present study attempts to evaluate mixed-mode stress intensity factors (SIF) for di erent specimen con gurations using digital photoelasticity. For estimation of SIF form digital photoelasticity, a new algorithm is proposed to solve multi-parameter stress eld equations.
