“…Hawong et al (2003) also showed the influence of the angle of notch on the distribution of the shear deformation field by using photo-elastic measurements on an isotropic material (resin). The analysis of unidirectional rupture of Iosipescu specimens at 0°leads to the conclusion that the value of shear strength cannot be directly determined with this test.…”

The direct determination of shear characteristics of concrete by universal tests is still a major concern for researchers. Most available studies use a torque that is applied to a hollow cylinder with a thickness/radius ratio as small as possible. This serves to develop a test based on the behaviour of the material and not the structure. However, these tests may show dispersions due to problems of fragility or non-homogeneity of the material.For this, an original experimental device has been used by creating two stress free zones using two Styrofoam pieces added to the cylindrical mold. New boundary conditions are created to transform the compression stress into shear on a limited area. The device ensures the perpendicularity of the cylinder and the good distribution and homogeneity of constraints.Using this technique allows the determination of the influence of the failure surface inclination on the behaviour of concrete in shear.

“…Research has been done in an attempt to modify the Iosipescu shear fixture to reduce the effects of the unwanted deformations. 21,22 Research has also been done to improve the specimen geometry, specifically the notch geometry. 23 The conclusion is typically that the notch geometry is dependent on the degree of the in-plane isotropy of the composite.…”

Test procedures for characterizing the orthotropic behavior of a unidirectional composite at room temperature and quasi-static loading conditions are developed and discussed. The resulting data consisting of 12 stress–strain curves and associated material parameters are used in a newly developed material model—an orthotropic elasto-plastic constitutive model that is driven by tabulated stress–strain curves and other material properties that allow for the elastic and inelastic deformation model to be combined with damage and failure models. A unidirectional composite—T800/F3900, commonly used in the aerospace industry, is used to illustrate how the experimental procedures are developed and used. The generated data are then used to model a dynamic impact test. Results show that the developed framework implemented into a special version of LS-DYNA yields reasonably accurate predictions of the structural behavior.

“…The value of the equivalent stress close to points U and V (notch roots) depends on the material properties and on the geometrical parameters of the specimen. Some previous numerical studies have also underlined this phenomenon [24][25][26][27]. Fig.…”

Composite materials are a key element in weight reduction strategies, so the analysis of the mechanical behavior of assemblies of composite modules is of great importance. Failure initiation in bonded assemblies involving composites is often associated with crack initiation in the adhesive or delamination of the composite plies close to the adhesive joint, caused by interlaminar or throughthickness stresses. Thus, the analysis of the behavior of composites and their assemblies under outof-plane loadings is necessary in order to optimize such structures. However, few experimental devices are proposed in the literature and they often require thick composite specimens which are not representative of most industrial applications. This paper describes the use of a modified Arcan test to determine the behavior of composites and hybrid bonded assemblies over a wide range of tensileshear out-of-plane loadings. The key advantages of this fixture are the testing of thin composite plates and the use of an adhesive to fix samples. Moreover, an optimization of the design of the proposed device, based on finite element simulations, significantly limits the influence of edge effects in order to obtain accurate experimental results. Some test results are presented which underline the potential of the proposed approach.
