摘要: Abstract Previous experimental and numerical investigations have shown that expansion tubes under axial compression by a conical-cylindrical die had stable efficient energy absorption characteristics [1]. In order to further understand the mechanisms of such tube process, theoretical analysis is given in this paper. The material assumed be rigid, linear hardening rigid. When gradually pushed in, expands. Both radial deflection wall required driving force vary with stroke their expressions are obtained theoretically. final radius steady-state estimated. explains three deformation modes observed experiments [1]: tip-conical surface contact mode (T-C mode), wall-conical (W-C cylindrical (W-CC depending on values geometrical parameters die, as ratio thickness h/R0 semi-angle γ. Deformation each discussed map phases h − γ plane results compared data, reasonably good agreement. addition, an early stage using elastic, model demonstrates elastic negligible.
