Transverse impact response of movable fiber bundle with constant resistance

Long fiber bundles are the promising candidates of manufacturing advanced composite materials again impact loading and producing the dragging media to brake a high-speed moving object. Here, transverse impact response of a movable long fiber bundle is the key scientific challenge for solving the engineering problems, where the constant resistance should be considered. In this paper, the transverse impact response of a movable elastic-plastic fiber bundle carried out by a rigid ball as high-speed object is numerically investigated. The mechanical modelling that involves the propagation of stress wave along fiber bundle, the motion of fiber bundle and the deformation of fiber bundle is established. Meanwhile, the mathematic deductions are presented that indicate the inherent physical mechanisms and accordingly the analytical solutions are given. Thus, with timing, the velocity, acceleration and displacement of the ball, the stress, strain as well as the displacement and configuration of fiber bundle and the mechanical energy transformation are quantificationally given. Correspondingly, the panoramic view of the transverse impact process is presented. This work presents a numerical method to solve the transverse impact response of movable fiber bundle with constant resistance for designing the high-performance long fiber composites and additionally developing the dragging-to-braking engineering as well.
