| Abstract: | Geometrical nonlinearity, contact nonlinearity and material nonlinearity caused by impact large deformation are considered. The finite element model is built to simulate the axial impacts of composite material tubes. The impact energy absorption behavior of glass/epoxy tubes is analyzed. The calculation results agree well with the experiments, which assures the validity of this finite element model. The effects of lay angle on energy absorption capability of composite material tubes are studied. |
