elastic modulus, numerous set of statically admissible and kinematically admissible distributions can be generated, and both lower and upper bounds on limit loads can be obtained. This paper demonstrates the application of EMAP in the context of limit load determination of cracked
components. The procedure is initially applied to some practical components with cracks to verify their effectiveness in analyzing crack geometries. The analysis is then directed to pipe geometries containing multiple cracks representing typical stress corrosion colonies. The limit load results are then compared to traditional nonlinear finite element analysis results or analytical solutions.
