Strain Concentration and Failure Analysis of Notched Composite Laminates Under Tensile Loading
The influence of different shapes of centre notches on the tensile mechanical behavior of composite laminates was investigated by tension tests of composite laminates with circular notch and oblong notch. The strain concentration and failure process of notched specimens around the notch were analyze...

| description | The influence of different shapes of centre notches on the tensile mechanical behavior of composite laminates was investigated by tension tests of composite laminates with circular notch and oblong notch. The strain concentration and failure process of notched specimens around the notch were analyzed intuitively with the strain distribution rule obtained during the tension test. A progressive damage model based on continuous stiffness degradation criterion was also developed to investigate the damage propagation processes of notched composite laminates. The results indicate that the proposed progressive damage model can accurately describe the tensile failure of notched specimens; and the strain concentration factor induced by oblong notch is more remarkable compared to that induced by circular notch, but the strain gradient around the oblong notch is larger; while the damage processes of the two types of notched specimens are quite different, the tensile strengths of both notched specimens are close. |
