heal.abstract	Fatigue crack growth of foam core sandwich beams loaded in flexure has been investigated numerically. Extensive fatigue data from foam core sandwich composites under flexural loading were analyzed. A static finite element analysis is adopted for the uncracked sandwich beam in order to predict crack initiation positions. A face/core debond parallel to the beam axis is considered in accordance with experimental data. A static two-dimensional finite element analysis of the cracked sandwich beam is accounted for the evaluation of stress intensity factors at the crack tips investigating the crack growth behavior. In this way it is succeeded in making a significant contribution to understand the initiation and propagation of a fatigue crack in the foam core of sandwich beams loaded by flexural loading. © SAGE Publications 2008.	en
