This paper describes an experimental investigation of the elastic dynamic buckling of carbon fiber reinforced plastic cylindrical shells subjected to pulse axial compression. The critical impulse is applied using a horizontal crash sled, so to obtain axial compression shape similar to a half-sine and duration of the impact load of approximately 0.1 s.
