Elastic Response of Heat Generating Rod at a Variable Generating Rate
Eraslan, Ahmet Nedim; Varlı, Ekin (2014-09-28)
The aim of this study is to develop a computational model to analyze thermally induced stress and deformation in a heat generating solid rod. The rod is initially at zero temperature, but for times greater than zero heat is generated internally at both space and time dependent rate. As the rod is heated up slowly an uncoupled solution is realized. The heat conduction equation with a variable generation rate is solved by a finite element collocation method. Two different generation rates are handled. The num...
ELASTIC-PLASTIC EXPANSION OF A SPHERICAL-SHELL WITH NONLINEAR HARDENING
GAMER, U; TEKKAYA, AE (1989-01-01)
Subject of this paper is the quasi-analytical treatment of the elastic-plastic spherical shell whose inner surface is heated slowly. The hardening behavior of the material is presumed isotropic, but it need not be specified beyond that. A first plastic region forms at the inner surface, and, for not too thick-walled shells, a second plastic region appears at the outer surface. The general results are specialized to linear hardening and thereafter to Swift's hardening law with the power one half. Numerical r...
Elastic-plastic deformation of a heat generating tube with temperature-dependent yield stress
Gulgec, M; Orcan, Y (2000-01-01)
The distribution of stress, plastic strain and displacement in an elastic-perfectly plastic tube with fixed ends in the presence of a uniform heat source is investigated analytically by taking into consideration the temperature dependence of the yield limit. The treatment is based on Tresca's yield condition and its associated flow rule. Depending on the radius ratio of the tube, in general, five different plastic regions, two of them corresponding to an edge regime of Tresca's prism, and an intermediate el...
ELASTIC-PLASTIC DEFORMATION OF A CENTRALLY HEATED CYLINDER
ORCAN, Y; GAMER, U (Springer Science and Business Media LLC, 1991-01-01)
Subject of the investigation is the deformation of a perfectly plastic cylinder with uniform temperature inside its cylindrical core and zero surface temperature. The calculation is based on Tresca's yield condition and the flow rule associated to it. For small radii of the hot core. a plastic region appears at the center and expands towards the surface of the cylinder with increasing core temperature. The other possibility is that, depending on the core radius, two plastic regions form one after the other ...
Elastic-plastic deformation of a rotating solid disk of exponentially varying thickness
Eraslan, Ahmet Nedim (2002-07-01)
The elastic-plastic deformation of a rotating solid disk of variable thickness in exponential form is investigated using Tresca's yield criterion, its associated flow rule and linear strain hardening. An analytical solution is obtained and numerical results are presented for different values of the geometric parameters. In the limiting case of uniform thickness the solution reduces to Garner's solution.
