The apparent weakening of a uniaxially tensioned infinite domain that contains a single spherical void and is anywhere else filled with a homogeneous and linear elastic material is investigated through two Finite Fracture Mechanics approaches. Result

International audience; Mixed mode crack initiation in PMMA specimens containing square holes is investigated experimentally by uniaxial tensile tests. The crack deflection with respect to the V-notch bisector and the failure load both increase for d

Interfacial debonding in fiber-reinforced composites is a common problem, especially in external strengthening techniques. This investigation aims to determine the load during debonding, and discusses two practical design parameters for direct shear

The brittle or quasi-brittle failure initiation at sharp V-notches under mode III loading conditions is investigated by means of the coupled Finite Fracture Mechanics (FFM) approach. The model is developed by assuming that failure is shear stress gov

Two nonlocal approaches are applied to the borehole geometry, i.e. a circular hole in an infinite elastic medium subjected to internal pressure. The former approach lays in the framework of Gradient Elasticity (GE), which results nonlocal in the stri

The decrease of the apparent uniaxial tensile strength resulting from a single flawless spherical cavity in an infinite linear elastic continuum under uniaxial tension is investigated. To this end, a new generalized semianalytical expression for the

In the present contribution, the coupled stress-energy criterion of Finite Fracture Mechanics (FFM) is applied to assess the fatigue limit of structures weakened by sharp V- and U-notches and subjected to mode I loading conditions. The FFM is a criti

The fatigue limit of structures containing V- and U-notches is assessed through the coupled stress-energy criterion of Finite Fracture Mechanics (FFM). The analysis is limited to mode I loading conditions. The FFM criterion is a critical-distance-bas
