Theories of failure average stress criterion and point stress criterion in notched fiber-reinforced plastic
The present work aims to analyze a study on the mechanical response of fiber-reinforced plastics in the presence of geometric discontinuity, as a result of the uniaxial tensile test. The geometric discontinuity is characterized by the presence of a circular hole in the longitudinal section of the co...

| description | The present work aims to analyze a study on the mechanical response of fiber-reinforced plastics in the presence of geometric discontinuity, as a result of the uniaxial tensile test. The geometric discontinuity is characterized by the presence of a circular hole in the longitudinal section of the composite. In this study, two different types of configurations are tested: one reinforced with glass/E fibers and the other is a hybrid reinforced with glass/E and jute fibers, with and without a hole, aiming to provide a better agreement on mechanical properties, regarding the residual strength. The residual strength determined using normative rules is used in the point stress criterion and average stress criterion failure theories for the semiempirical calculation of distances (d0 and a0) in the boundary of hole, area of failure stress. The results show the direct influence of the presence of geometric discontinuity and residual strength in all studied parameters since the direction of reinforcement in relation to application of the load is maintained regardless of hybridization. |
