Prediction of Fracture Behavior by Image Processing

Abstract

The failure of structure leads to the loss of money but more importantly, the loss of life. Failures occur for many reasons, including uncertainties in the loading or environment, defects in the materials, propagation of fractures, inadequacies in design, and deficiencies in construction or maintenance. Fracture is one of the most important factors that leads to the failure of the whole structure. Many people have investigated the subject of fracture mechanics and proposed their solutions. Their solutions are based mainly on theories and experiments. In this thesis report a new way of investigating fracture behavior is studied by Matlab image processing. A simple Matlab code has been developed to detect cracks of a surface and to find the length of the cracks. Comparing the results of the code with the theoretical results given by Griffith the behavior of fracture has been predicted.
