Graphite/Epoxy 스트링거의 크리플링 실험
Crippling Test of Graphite/Epoxy Stringers
초록
In author's previous paper, a finite element algorithm was presented to calculate the buckling and crippling stresses of composite laminated stringers. In this study, for the validation of the finite element analysis, Z-section composite stringers of different lengths and flange-widths were tested in axial compression. The stacking sequence of graphite/epoxy is [
