=For each analysis; the tensile strains were caladatod from the deformed spacing betw, <br /> adjacent grid points in the surface against the initial grid spacing. A characteristic curve o`' <br /> maximum tensile strains versus ratio of void width (4) to controlled fill thickness r"` <br /> developed from the analyses' results.
