This paper investigates the identification of the location of delamination of CFRP laminates by using the response surface method. New technique is proposed that can reduce the required experimental cost by performing the analyses instead of experiments. The new delamination FEM model is proposed based on the detailed observation of actual delamination to perform FEM analysis that approximate the experimental result. As a result, the response surface is unstable for the experimental error when only FEM results are used to make the response surface. Newly proposed Robust Response Surface whose explanatory variables include the artificial noise can successfully improve the unstability and its applicability was confirmed by performing the identification of delamination location of CFRP laminate.
