Abstract
The proliferation of powerful personal computing systems has made viable the creation of software programs to determine the fracture mechanics characteristics of engineering materials in various configurations, replacing bulky and time consuming handbooks. This report compares four such programs; NASCRAC, pc-CRACK, Fracture Mechanics and Damage Tolerance Analysis Software (FM&DT) and PC-Failure Assessment Diagram (PC-FAD). A brief description of each package and a review of their respective features is presented. Each package was rated in terms of their various capabilities and functionality. Comparisons were made based on itsm such as number and types of geometries, materials libraries, analysis methods, fatigue crack growth capabilities, user interface, user manuals and system requirements. Several representative test problems were attempted with each code to verify accuracy and to highlight limitations. The code NASCRAC proved superior in many categories with pc-CRACK as a close second. FM&DT suffered from a very poor user interface and PC-FAD was limited in its functionality.
