Fatigue property evaluation of 7075/6061 aluminum alloy TIG welded overlap joints

Constant-amplitude fatigue tests were conducted on overlap specimens of 7075/6061 aluminum alloy TIG fillet weldes. Subsequently, detailed finite element models were developed based on both the hot spot stress method and the critical distance method. The range of maximum principal stress variation w...
