【正文】 bending, the span for the x direction, both the bending stiffness and the shear stiffness of the metal honeyb sandwich panel decrease along with the defect dimension increasing, and the skewed pressing and stretching, under the tensile load in the z direction, the strength of the structure is linear attenuation along with defect dimension increasing, however under the pression load the surfacecore connecting defect has no effect on the structureIn order to characterize the failure modes of damage of the honeyb sandwich panel on the surfacecore debonding, we establish the threedimension interface element model based on the cohesion model. By using ABAQUS user subroutine UEL we developed the threedimension interface element. By determining the curve of the opening displacement with the bridging stress could simulate the debonding of the surfacecore.【關鍵詞】金屬蜂窩夾層結構 缺陷 有限元法 界面單元【英文關鍵詞】Metal honeyb sandwich panel Defect Finite element met
