Experimental and Numerical Study of Delaminaiton Growth Induced by a Transverse Crack in Unidirectional Lamiantes Subjected to Bending Loads

摘要

This paper presents the results of an experimentla and numerical investigwation into the mixed-mode delamination growht inititated from a transverse crack in unidirectional laminates under the three-point-bend test condition. The delamination growht was found to be stabl both numerically and experimentally. Two data reduction methods, the compliance calibration and the finiteelement-based data reduction, were used to analyze test resutls. It was shown that the latter method gives better results.
