Viscoelastic Cylindrical Pressure Vessel With Variable Inner Radius, A. N. Joshi
Electronic Theses and Dissertations
The objective of this thesis is to predict from a theoretical basis the stress redistribution processes occurring within the viscoelastic core of a cylindrical pressure vessel reinforced by an elastic casing around the outer perimeter, and subject to internal pressure applied to the time-dependent inner boundary of the cylinder. The problem so stated requires development of a new technique leading to a solution for a mixed boundary value problem for a viscoelastic body occupying an ablating cylindrical y-shaped region. The approach taken in this thesis consists in reduction of a governing integro-differential equation to an equivalent set of algebraic equ3tions …
