heal.abstract	The present paper is concerned with numerical studies of sandwich T-joints which are formed by two panels connected by lap joints. Sandwich GRP skin/PVC core panels are attractive structural components in high speed marine vehicles, especially due to their efficiency to carrying uniform lateral loading. The behaviour of such joints is very complex since it involves several types of materials such as GRP, foam material as well as glue filler, and a geometry with potential high stress concentrations. In this study, a brief review of the problem is first presented and areas of principal interest which most influence joint behaviour are identified. Based on fracture mechanical considerations, a numerical crack design procedure has been developed. Finally, numerical results are presented for the J-integral values in the case of T-joints subjected to lateral loads.	en
