Effect of notch on mechanical property of 6063 aluminum alloy
To investigate the effect of notches on the mechanical properties of 6063 aluminum alloy,five different specimens with single notch and double notches(the space of the two notches is 1.0,2.0,3.0,and 4.0 mm,respectively)are designed,and its mechanical properties are analyzed using room temperature uniaxial tension experiment combined with numerical simulation method.The results show that the local notch cause a significant decrease in the plasticity of the plate and a significant reduction in fracture displacement;the stress of specimens with notch/notches is higher,and its stress concentration is more serious.
