Damage evaluation of ABS specimen simply notched subjected to uniaxial loading by static damage method and by probability density of rupture

ABSTRACT Due to complex combinations of loading, the materials submit a damage which is manifested by the appearance of defaults. These defaults spread gradually to a fatal fracture of the material. It follows that the life of the material is determinated by their resistance to the propagation of defects. For a good prediction of the components life in the industry and in order to avoid any sudden disruption in service, it is necessary to understand the mechanisms of damage. This manuscript presents study of the ABS material’s damage having an artificial default and submitted to tensile loading, adopting three parts. The first part will present the experimental methodology of tensile tests for a rectangular beam from ABS material having a notch. The second part will be devoted to the evaluation of static damage depending on the size of the default. And the last part will be devoted to a study by failure probability density. The damage’s evaluation by calculating of damage static-reliability has identified the different stages of damage to our structure starting from the initial stage to the final stage which is related to the total deterioration of the beam.
