Notched tensile strength of various fibre reinforced metal laminates

Abstract

Modifications in Whitney-Nuismer (WN) fracture models known as the point stress criterion and the average stress criterion are proposed for notched strength estimations of laminates. Applicability of theproposed procedure is examined by considering the residual strength data on carbon fibre reinforced metal laminates, aramid reinforced aluminium laminates and glass fibre reinforced aluminium laminateshaving saw-cuts and circular holes of various sizes. The analytical results obtained in the present study are close to the test results. This study confirms that the present modification in WN fracturemodels for fibre reinforced composites can be used for notched strength evaluation of FRMLs. © 2000 Taylor & Francis Group, LLC.
