Ahmed et al. / Investigation of the Energy Absorption Characteristics of Metallic Tubes with Curvy Stiffeners under Dynamic Axial Crushing Latin American Journal of Solids and Structures 14 (2017) 1443-1463 In this study, nature of -cells is exploited in single and bi-tubular metallic tubes by using

  • QUASI-STATIC AXIAL CRUSHING BEHAVIOR OF ALUMINUM .

    The axial crushing behavior of empty and Al close-cell foam-filled Al -tube designs (hexagonal and square) and E-glass woven fabric polyester composite and Al hybrid tubes were investigated through quasi-static compression testing.

  • Energy-absorbing effectiveness factor

    the dimensionless parameter has been examined for the static and dynamic axial crushing behaviour of thin-walled sections. The influence of foam fillings and the stiffening of circular and square tubes is examined. It transpires that, according to the energy-absorbing effectiveness factor, an axially crushed

  • Crashworthiness design of -cell tapered tubes using ...

    In this article, crashworthiness performance and crushing behavior of tapered structures with four internal reinforcing plates under axial and oblique dynamic loadings have been investigated. These structures have a tapered form with five cross sections of square, hexagonal, octagonal, decagon and circular shape. In the first step, finite element simulations performed in LS-DYNA were validated ...
