Experimental-analytical comparison of the ductile failure of notched tensile bars
Experimental results of the ductile failure of 7075-T6 aluminum notched tensile bars are compared with finite strain, nonlinear, finite element calculations. This comparison allows the investigation of mean stress dependent macroscopic theories for ductile fracture. Two such theories are examined and the results are presented in graphical form. 14 figures, 2 tables.
