초경량/고강성을 가진 ISB판넬의 굽힘강성 및 파단모드에 관한 연구

The objective of this research work is to investigate into characteristics of bending stiffness and failure mode for the ISB ultra-lightweight panel with internally structured material The expanded metal with a pyramid shape and woven metal are employed as an internally structured material In order to investigate the characteristics, the specific stiffness and failure map are estimated using the results of three-points bending test From the results of the experiment, the influence of design parameters of ISB panel on the specific stiffness and failure mode has been found. In addition, iIt has been shown that ISB panel with expanded metal is prefer to that with woven metal from the view point of optimal design for ISB panel.
