Influence of thickness and notch size on eccentrically loaded single edge notch aluminium plates

摘要

The mechanism failure in thin Al 8011 aluminium plates has been experimentally investigated. Experimentations have been carried out on pin-loaded single-edge-notched (SEN) tensile specimen with varied notch size, plate thickness and material conditions. The results have shown that the failure of eccentrically loaded edge notch specimens is a typical combination of tensile and bending loads. It is also seen that age hardening has reduced the load-carrying capacity of the plates. The fractographic analysis has been made to identify the nature of failure as a function of plate thickness, notch size and the material conditions. The specimen preparation and the experimentations have been carried out according to the ASTM standards.
