Research abstract

Fracture mechanics capabilities based on finite element multidisciplinary analysis will be designed and developed. Incorporating finite element based fracture mechanics analysis will enhance the power and strength of the MDFEM software. An in depth literature survey will be conducted to assess the appropriate finite element methodology for modeling crack tip stress regions and associated material constitutive relations. In order to characterize fracture behavior, crack tip finite elements, crack tip opening displacement and J-integral methods will be implemented. Software to perform these fracture related parameters will be developed and tested with benchmark problems.
