Section 11.5.3. Cracks2000 Structural Integrity Software

The CRACKS2000 program is based on the Linear Elastic Fracture Mechanics (LEFM) approach for estimating the fatigue life of a component with a crack.  The LEFM approach uses the stress intensity factor parameter, as the driving factor for crack growth.  The Cracks2000 program has considerable flexibility in the analytical modeling of crack growth analysis problems.

Cracks2000 has fifty-one stress intensity factors solutions.  There are closed form equations for stress intensity factor solutions for 25 geometries.  Many of these solutions are the early Newman-Raju solutions, which are retained for comparisons with older analysis.  For the latest stress intensity factor solutions, tables of b-factors are generated from the equations;  the tables are used for the life analysis, and can be printed and plotted for b-factors comparison
