Abstract

The present article is concerned with nonlinear fracture behavior of single cantilever beam made of unidirectional fiber-reinforced polymer composite. A theoretical study is performed assuming that the composite follows the stress–strain relation of an elastic-perfectly plastic material in both tension and compression. For this purpose, a model based on mechanics of materials is used. The fracture investigation is performed using path-independent J-integral where the contour of integration is chosen to coincide with the beam contour. Several closed-form analytical solutions that correspond to different ratios between crack length and beam length are obtained. It is shown that when the material nonlinearity is taken into account, an increase in J-integral value is observed. This finding is attributed to the increase in strain energy dissipation due to nonlinear deformation.
