Low-Velocity Impact Simulation of Open Ended Filament Wound Composite Tubes

In this study, dynamic response of low-velocity impact of E-glass/epoxy filament wound composite tubes was investigated. Applied method is Finite Element Method and it is based on theoretical studies and interpreting computer analyses results. A commercial software (ANSYS-LSDyna) was used for the simulation. Open ended filament wound composite tube and impact phenomenon were modeled. Diameter of hemispherical impactor is 24 mm and mass is 6.35 kg. Investigation has been carried out for 2, 2,5 and 3 m/s impact velocities. 6, 8 and 10 plies filament wound composite tubes with [+55°,−55°]3, [+55°,−55°]4, [+55°,−55°]5 stacking sequences and 72 mm in diameter were used. They were positioned in V-block. Force-time history, energy, velocity-time diagram that depend on the base of data will be plotted. Obtained values were interpreted.
