Abstract： Abstract: Experimental tests were conducted on pseudo-elastic phase transformation cylindrical shells (PTCSs) with different LDR under single pulse loading using a modified split Hopkinson pressure bar (SHPB) apparatus. It was found that PTCSs with different LDR have different buckling modes by the high speed camera and loacal strain measured by the strain gauges. The PTH of the PTCS is characterized by the following: 1.Recoverability; 2.the phase transformation hinge appears on the microsecond-grade time that is coupled with the fluctuation effect and its deformation is fluctuant; 3.there are a number of PTHs in the PTCS under impact loading, including circumferential phase transformation hinges, axial phase transformation hinge, diagonal transformation hinge.
