摘要: Abstract Numerical simulations were carried out in order to obtain the stress concentrations induced by simulated hemispherical pits with 500 µm of diameter on square plates 100 mm2 aluminum alloy 7075-T651, for three different plate thickness: 0.7, 1.6 and 3 mm. The pertinence this study is supported fact that modern industries using alloy, such as aeronautical, marine, mold tool manufacturing arms industries, are affected combination loading corrosion, which leads concentration failure material. performed investigate effect one two surface plates, transverse or longitudinal load orientation under uni-axial biaxial loading. In addition, depth across thickness together proximity last described conditions investigated. It was found regards applied plays a significant role uniaxial Finally, graphs corresponding general tendencies obtained associated mentioned parameters conclusions concerning these numerical results.
