LONGITUDINAL IMPACT OF A SEMI-INFINITE CYLINDRICAL VISCOELASTIC SHELL,
Abstract
The response generated by the longitudinal impact of a semi-infinite, cylindrical, viscoelastic shell is investigated on the basis of membrane theory. Laplace transform methods are applied and asymptotic values of the axial stress are determined for large values of a nondimensional time. A real integral which appears in the asymptotic expressions is evaluated numerically and tabulated as a function of two parameters. In the equivalent elastic problem, oscillatory solutions were obtained with peak values of the stress exceeding those found in the impact of a thin elastic rod. The present study indicates that the oscillations and overshoots no longer occur in the asymptotic solution for a visco elastic material. The results obtained also give the asymptotic solution for a viscoelastic rod. (Author)
