%X A model,based on SEM micrograph of replica and observation,is prsesent-ed in this paper for the analysis of stiffness reduction of composite laminates due todebonding of the interface between fiber and matrix.The method of isoparametric elementswith eight nodes is employed.The results show that measureable reduchions in stiffress ac-company fiber breakage if debonding occurs.The conclusion is that debonding has a majoreffect on stiffness.
