The Characteristics of Collapse for Thin-Walled Members by Inclined Impact Load

In this study the characteristics of the inclined impact collapse for the thin-walled members were studied as follows: The basic equation of the viscoplastic constitutive relation after the local buckling in the thin-walled members was shown. The equation was applied to the case of collapse far thin- walled members by the inclined impact bad. The influences of the local deformation, the restrain and the friction at the loading contact point were obtained by experiments. The experiments far inclined impact collapse were done and the dependencies of deformation rate of the members were shown.
