알루미늄 폼의 접착부에서의 경사각도별 전단 특성에 관한 해석 연구 A study of Analysis on shear property due to inclined angle at bonded surface of aluminum foam
pp.1267-1272
In this study, tapered double cantilever beam bonded with aluminum foam composite is modelled and analyzed by finite element analysis. The bonding strength on Mode II of this structure is evaluated and investigated. In cases of inclined angles of 6°, 8° and 10°, maximum equivalent stresses occur 1.29, 1.59 and 2.6 MPa respectively at the range of forced displacement of 5 to 6 mm. And maximum reaction forces become 186, 208 and 235 N individually at this range of displacement in these cases. By the analysis result on 3 kinds of models, the maximum reaction load increases as angle of inclination of model increases. And the elapsed time to approach the maximum load and the time to disappear away become shorter. This study result can be applied into the real composite structure with aluminum foam in case that the surface bonded with adhesive is inclined. This fracture behavior can also be investigated and the impact property can be examined
