The inversion tube experiment
WebThe use of an inversion tube to absorb energy is suggested in reference 2 and applications of the inversion tube in a lunar landing system are discussed in reference 3. The inversion process involves the turning inside out of a tube acted upon by a compressive load. Experimental results indicate that the process is WebSep 1, 2015 · From theoretical analysis and experimental observations, the tube inversion using a die is feasible only for a certain range of tube thickness-to-radius ratios, and only for a suitably profiled die [1]. Finite element simulations were also carried out for detail investigations of the inversion tubes using a die [12], [18], [19].
