Abstract

Abstract

TiNi tubes with and without lateral constraint subjected to radial impact were investigated experimentally for the purpose of developing repeatedly used energy absorption devices.By using a modified SHPB apparatus and wave separation technique, the signal recorded was extended to about 3ms, and then the load-compression curves were available.With a high speed CCD camera, the dynamic deformation process of the specimens was captured.The results show that TiNi tubes without lateral constraint have an excellent recoverable deformability with apparent loading platform.The tubes with lateral constraint have a much better performance of energy dissipation and are able to withstand higher speed impact.If properly choosing the combination of two constraints, it may improve its dynamic performance both in the large deformation and high energy dissipation and will be used in the future shock absorbing devices.
