EXPERIMENTAL AND NUMERICAL INVESTIGATION OF THE FAILURE MECHANISMS IN THE OHC TEST. INFLUENCE OF LAY-UP AND STACKING SEQUENCE

摘要

The aircraft industry's use of composite materials is increasing significantly to leverage weight savings and to optimise material performance against often stringent design allowables. The aim of this study was to understand-at a fundamental level-the parameters influencing open-hole compression (OHC) properties and to use the learning to develop a new generation of materials with an improved balance of damage tolerance and notched properties. The evolution of the failure was investigated experimentally and simulated using non-linear finite element modelling.
