TENSILE TESTING OF REPAIRED COMPOSITE SPECIMENS WITH DIC MEASUREMENT AND FEM CORRELATION

Mustafa EKREN and Prof.Dr. Altan KAYRAN

Repairs of composite structures are widely used in the aerospace industry and aerospace researches. There are many analytical and numerical studies in literature. For validation of the analyses test correlations are mandatory. Preparing repaired composite test specimens requires specific procedure to represent the repair conditions in actual structures. Abaqus a widely used commercial finite element package in the aerospace industry and aerospace researches is utilized for numerical analyses. In this article, detailed procedure for preparation of wet layup repaired composite specimens, implementation of DIC system on tensile tests of different types of repaired composite specimens and comparative study of the results with the finite element analysis to validate the outcome of the numerical results is presented.
