Notch-strengthening in two-dimensional foams

Abstract
Metallic foams show notch-strengthening behavior when analyzing double-edge notched specimen in compression and tension. A discrete microstructural model has been used to simulate the effect of notch depth and specimen size on the net-section-strength. The non-uniform deformation behavior is analyzed by using a strain mapping procedure, highlighting that strain tends to localize in discrete bands connecting the notch tips. The net-section-strength increases with increasing notch-depth and decreasing specimen size.
