The exact solution of the distribution of stress and deformation in an elastic-perfectly plastic cylindrical rod with uniform internal heat generation under generalized plane strain condition is presented. The treatment is based on Tresca's yield condition and the associated flow rule. The stress image points of the outer and inner plastic regions lie on two different edges of Tresca prism. With increasing heat generation parameter, the image points of the intermediate regions spread out through two side regimes and meet at another edge regime in the fully plastic state.

On annular disks of variable thickness subjected to external pressure Eraslan, Ahmet Nedim (Springer Science and Business Media LLC, 2004-02-01) Exact solutions are obtained for the elastic stress distribution in variable thickness annular disks under external pressure. Two different thickness functions both in parabolic form are considered. It is shown that, depending on the geometric parameters describing the shape of the disk profile, the plastic deformation in the variable thickness annular disk commences at the inner or at the outer or simultaneously at both surfaces. The critical values of the geometric parameters which cause the plastic defor...
Yielding of two-layer shrink-fitted composite tubes subject to radial pressure Eraslan, Ahmet Nedim (Springer Science and Business Media LLC, 2005-12-01) Yielding of two-layer shrink-fitted composite tubes with axially constrained ends subject to either internal or external pressure is investigated in detail. In the framework of small deformations, a state of plane strain and von Mises yield criterion, analytical expressions are obtained for critical values of the pressure leading to plastic flow. It is shown that, depending on material properties and tube dimensions, different modes of plastic deformation may occur. Yielding may commence at the inner tube o...
COMPRESSIBLE, HYPERELASTIC SPINNING TUBES SUBJECTED TO CIRCUMFERENTIAL SHEAR ERTEPINAR, A (Elsevier BV, 1991-01-01) The finite strain behavior of cylindrical tubes, made of a polynomial compressible material and subjected to the simultaneous action of constant spin and uniform external circumferential shear, is investigated using the theory of finite elasticity. The inner surface of the tube is assumed to be perfectly bonded to a rigid shaft. The governing quasi-linear system of two ordinary differential equations is solved using a shooting method. Numerical results are generated to analyze, qualitatively, the effects...
EXPERIMENTAL-STUDY OF UNSTEADY FORCED-CONVECTION IN A DUCT WITH AND WITHOUT ARRAYS OF BLOCK-LIKE ELECTRONIC COMPONENTS LI, W; KAKAC, S; HATAY, FF; OSKAY, R (Springer Science and Business Media LLC, 1993-01-01) An experimental apparatus was designed, built and used to study the behavior of transient forced convection in a rectangular duct with and without barriers due to a sinusoidal heat input at the inlet. to simulate the electric heating and cooling inside the computer. A wide range of Reynolds number (400 less-than-or-equal-to Re less-than-or-equal-to 20,000) and inlet frequencies (0.01 Hz less-than-or-equal-to beta less-than-or-equal-to 0.08 Hz) was covered in this experimental study for both laminar and turb...
Tresca's yield criterion and linearly hardening rotating solid disks having hyperbolic profiles Eraslan, Ahmet Nedim (Springer Science and Business Media LLC, 2004-12-01) An analytical solution for the stress distribution in rotating hyperbolic solid disk is obtained under plane stress assumption. The analysis is based on Tresca's yield criterion, its associated flow rule and linear strain hardening material behavior. It is shown that the deformation behavior of the hyperbolic solid disk is different from that of the constant thickness disk. The plastic core consists of three different plastic regions with different mathematical forms of the yield criterion. Accordingly, thr...
