Study on aluminum honeycomb sandwich panels with random skin/core weld defects:

摘要: Effects of random skin/core weld defects on out-of-plane tensile, compressive and in-plane shear behaviors of hexagonal cell aluminum honeycomb sandwich panels are investigated using ABAQUS/Explicit code. Firstly, a meso-structure model of the sandwich panels is constructed, which consists of the upper and lower skins, the honeycomb core and the skin/core welds. Defects are introduced by removing of skin/core welds, and the defect ratios are 1%, 2%, 4%, 8%, 16% and 32%. Next, the out-of-plane tensile, compressive and in …
