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
