In this work, the notch sensitivity behaviour of a 3D woven composite is analysed with the help of Digital Image Correlation. The composite architcture is characterized using oprical microscopie. Quasi-static tensile tests are done and a notch insensitivity behaviour is found for this material. To explain this, DIC strain pattern on the composite is analysed and in particular strains around the hole before failure using polar graphs. Damage developement is then investigated

Abstract
In this work, the notch sensitivity behaviour of a 3D woven composite is analysed with the help of Digital Image Correlation. The composite architcture is characterized using oprical microscopie. Quasi-static tensile tests are done and a notch insensitivity behaviour is found for this material. To explain this, DIC strain pattern on the composite is analysed and in particular strains around the hole before failure using polar graphs. Damage developement is then investigatedFile in questo prodotto:
