THERMAL STRESS INVESTIGATION OF SOLID PROPELLANT GRAINS. VOLUME 2 - MATHEMATICAL ANALYSIS
Abstract
The object of the present work is the investi gation into the problems of stress and deforma tion of linear viscoelastic solids under various environmental conditions, such as gravity, temperature and inertia forces. In the first chapter, the thermal stresses in viscoelastic solids with temperature dependent propertiesnvestigated, temperature dependence being limited to the thermorheologically simple type. The second chapter is occupied with the evalu ation of the effects of the acceleration terms on the stress distribution in incompressible viscoelastic solids, again under conditions of non-uniform transient temperature. The third chapter is devoted to gravitational effects. In appendix I the problem of an infinite slab and a solid sphere are solved numerically for the purpose of illustration and compared with exact solutions. In Appendix II error estimates con nected with one of the analytic methods are derived. In Appendix 2 the convergence of the first analytic method is established.
