Full textContinuous fiber composite materials have become extensively used in most engineering applications due to their high specific mechanical properties. Uniaxial tests are mostly used for the characterization of composite materials because of their simplicity and low cost. However, these tests are not adapted for the characterization of the behavior of these materials subjected to multiaxial stress state. For a better characterization of their behavior, biaxial tests were developed. Among different biaxial testing techniques, the in-plane biaxial testing of cruciform specimen is one of the most known methods. However, the main difficulty of this method is the design of a cruciform specimen that fails in the center. ln this work, a new cruciform specimen is designed for the biaxial tensile testing of plain-weave glass/epoxy composite. The final dimensions of the specimen are defined by a numerical parametric study while respecting some experimental constraints such as biaxial tensile machine capacity. An experimental validation is performed on two plain-weave glass/epoxy composites with different thicknesses. The tests were performed under different biaxial loading conditions. The strain distribution in the central zone of the specimen are obtained using the Digital Image Correlation (DIC) technique. The failure envelop is generated and compared to the predictions of three failure criteria (Max Stress, Max Stram, and Norris)

Full textSheet metal forming processes are widely adopted to produce panels, tubes, profiled parts in manufacturing industry. The numerical simulation of the forming processes requires accurate constitutive models of material. In many sheet metal working operations such as stamping, hydroforming, …, large strains and intermediate strain rates can be reached under biaxial strain or stress states. The objective of this work is to show the potential of the biaxial in-plane tensile test to characterize the hardening behaviour of metal sheets up to large strain levels. By numerical investigation, an optimal cruciform shape is designed to obtain large equivalent plastic strain, up to 30%, at the central zone under equi-biaxial strain path. As expected, the initial cracks of tested specimens are always observed at the central zone. Then, quasi-static and dynamic biaxial tensile tests on in-plane cross specimens have been performed on a dedicated servo-hydraulic machine. These biaxial tensile tests have been carried out on aluminium alloy AA5086 to validate the identification methodology of hardening behaviour under biaxial loading. This alloy has been chosen since its hardening behaviour is not dependent on the strain rate. Digital Image Correlation (DIC) technique is used for strain measurement. The parameters of isotropic hardening models are identified by inverse analysis based on the finite element model of the biaxial tensile test. Three yield criteria of Mises, Hill48 and Bron and Besson are compared for the parameter identification of different hardening laws. It is shown that the hardening law identified by biaxial test is precise only if an appropriate yield function is preliminarily determined. The biaxial flow stress curve identified with Bron and Besson yield function have been found in good agreement with the experimental flow stress curve obtained from uniaxial tensile tests. For biaxial tests at intermediate strain rates, damping layers are adopted to reduce oscillations on force versus time curves. The comparison of flow stress curves, identified from quasi-static and dynamic biaxial in-plane tensile tests on the non strain rate-dependent material AA5086, validates the identification methodology of strain-rate dependent hardening models. Finally, the proposed methodology is applied to the hardening characterization of a strain-rate dependent Dual Phase steel DP600 at room temperature. Identified biaxial flow stress curves have been compared with uniaxial ones for different strain rates ( . = 10-3s-1, 10-1s-1 and 101s-1). DP600 steel exhibits the same positive strain rate sensitivity for uniaxial and biaxial strain states. The biaxial flow stress curves identified on the basis of Ludwick and Voce hardening models are close, up to equivalent plastic strains of 30%. The benefits of the proposed methodology, based on a biaxial in-plane tensile test carried out on cross specimen, are clearly shown since the hardening behaviour identified in this case for large strains (up to 30%) is very different from the one identified from uniaxial tensile test on a smaller strain range

Full textSheet metal forming is very common in industry for producing various components. The optimal use of light alloys or high strength steels in transportation for energy economy, requires in-depth analysis of their formability. Usually, the formability of sheet metal is controlled by the onset of localized necking. However, under specific loadings (complex strain paths...), fracture characterizes the formability and the forming limit curve at fracture (FLCF) instead of the forming limit curve at necking (FLCN) should be considered. For identifying FLCN and FLCF under linear and non-linear strain paths, conventional methods require different experimental devices and geometrical specifications of specimen to cover a wide range of strain paths. However, using the in-plane biaxial tensile test with just one shape of cruciform is sufficient for that, even changes of strain path without unloading can be made during the test. The first objective of this study is to show that the in-plane biaxial tensile test with a single type of cruciform specimen permits to investigate the FLCN and FLCF of sheet metals under different linear and non-linear strain paths. Firstly, the forming limit strains at fracture of AA5086 sheet (t=4 mm) under linear and non-linear strain paths have been characterized, by testing an existed dedicated cruciform specimen. Thinner sheet metals are often used in industry, so a new shape of cruciform specimen with an original thickness of 2 mm was proposed. This specimen is successfully used to investigate the formability of DP600 sheet under linear and two types of non-linear strain paths. The second objective is to discuss the validity of commonly used ductile fracture criteria to predict the onset of fracture. Some ductile fracture criteria were used to produce numerical FLCFs for AA5086 and DP600 sheet. Finally, for the two tested materials, it is possible to find a criterion to predict the experimental FLCFs for either linear or non-linear strain paths

Full textFerritic stainless steels (AISI 441, AISI444, and Crofer 22 APU) were evaluated for the application as interconnects in SOFCs. The interested properties studied were growth kinetics, area specifie resistance (ASR) and adhesion of oxide scales formed on the steels ln the temperature range 700-900°C. The AISI 441 was selected as the competitive grade for this application, but it seemed necessary to improve its ASR. The further work was then to evaluate the influence of coatings on this property, with Ti, TiO2 and TiN deposition on AISI 441 by the magnetron sputtering technique. As supposed, doping of the chromia scale by titanium increased ASR without degrading the other properties to a negative extent. Basing on investigated properties, it was concluded that TiN-coated AISI 441 exhibited the best optimised properties to be applied as SOFCs interconnect
