Figure 4. Equivalent stress distribution on the cross sections of the pore-containing (A-C) and pore-free (D) samples, pores are 100 um in radius. Equivalent stress distribution of pore size and location on the Y axis negative direction from the edge to the center of the circle at 0.05 mm from the fixed point; (E) black dots are equivalent stress and (F) data were fitted using Equation (7). Blue dots are finite element simulation data, red dots are equation fitting data.
