Research Abstract

This research has been performed under the purpose of developing a three-dimensional fracture mechanics analysis software platform that enables us to carry out a collaborative software development.Under a standardized data format, we successfully developed a fully automatic crack propagation analysis software, a J-integral program for nonlinear fracture mechanics analysis and a data handling technique to deal with large scale fracture mechanics analysis. It has been proven that researchers and engineers can develop three-dimensional fracture mechanics software under a collaborative manner.
