【 摘 要 】

n this paper, afinite element modeling viaABAQUS/Explicit simulation on a novel fabrication miniature composite fuselage structureis presented. The fuselage structure is modeledas a continuum composite layup that consisted of a woven C-glass fiber/epoxy 200 g/m2composite laminated [908] with theorthotropic elastic material propertiesandadhesively bonded butt joint. The adhesively bonded joint progression is modeled usingcohesive elements technology. For the purpose of FEA modeling, an experiment of double cantilever beam (DCB) according to ASTM standard D5528 is performed to determine the adhesive mode-I critical toughness.The mode-I interlaminar fracture toughness data (GI) are calculated and compared by four different methods according to the ASTM standard: BT, beam theory, MBT, modified beam theory, CC, compliance calibration method and MCC, modified compliance calibration method. The results indicate thatABAQUS/Explicit is able to reproduce satisfactory adhesive joint behavior using cohesive elements and collapse modes under crushing process.
