Abstract (EN): In the framework of non-linear fracture mechanics, this study concentrates on the failure prediction of a bi-failure specimen made of Aluminum alloy AA6061-T6 under tensile loading state. Thus, it firstly aims to experimentally evaluate the specimen force/displacement response over a uniaxial tensile test. The mechanical behavior of the material in addition to the modified geometrical properties of the test specimen are fully described. To obtain the experimental data, an advanced optical technique, Digital Image Correlation (DIC), is used to evaluate the internal variables such as displacement in the presence of the failure phenomenon. To acquire the numerical assessment, the problem is modeled within the Finite Element (FE) formulation in ABAQUS (c) assuming a defined ductile damage criterion, Gurson-Tvergaard-Needleman (GTN), to attain the intended results. Successful numerical results obtained from FE were validated with experimental DIC data. Here, the failure evolution was perceived by DIC observations, allowing to explain the failure modes. Considering all acquired results, it can be concluded that the presented methodology is capable to predict the material damage and failure process. (C) 2017 The Authors. Published by Elsevier B.V.
