The influence of debond length on the buckling and wrinkling of sandwich beams under compressive load / Bambang K. Hadi

A two- and three-dimensional finite element analysis was carried out to analyze critical buckling loads of debonded sandwich beams. Both overall buckling and wrinkling were analyzed, using sandwich beams having 45 mm and 75 mm core thicknesses. The analysis shows that sandwich beams with 45 mm core...
