Design, Test and Analysis of Tensor Skin Panels for Improved Crashworthiness in211 Case of Water Impact

摘要

Within the framework of a European BRITE EURAM project, several partners work211u001etogether to evaluate and analyze 'tensor skin' panels. Tensor skin panels are 211u001edesigned to improve the crashworthiness of composite helicopters in case of 211u001eimpact on water, by providing a quasi-plastic deformation behavior. Tensor skin 211u001epanels were designed, fabricated and tested as well as several equivalent 211u001econventional honeycomb core sandwich panels with identical face sheets. The 211u001epanels were tested in static transverse load, static in-plane shear and at 211u001edynamic transverse impact. This paper presents the panel configurations, the test 211u001econditions and the test results as well as the numerical simulation of these 211u001etests.
