Abstract Penetration of syringe needles into the rubber plug of vials occurs daily in usual medical operation, but in nature, it is a complex mechanical process concerning the deformation, friction and failure of materials. Micro particles could be generated during the fracture process of plug and needle friction during penetration. Actually, the structural configuration of needle pin plays an important role besides of plug itself. In this work, mechanical behaviors of butyl rubber and needle material are obtained firstly, after performing various strain rate experiments based on Instron 5848 machine and Hopkinson bar technique. And their… More >
