Yielding of long concentric tubes under radial pressure based on von Mises criterion;
(2005) Akiş,T.; Eraslan,A.N.
The classical problem of a plain strain tube with free ends, subject to either internal or external pressure is extended to tightly fitted long concentric tubes with axially constrained ends. Making use of von Mises yield criterion, critical values of pressure leading to plastic flow are determined in terms of material properties and tube dimensions.

Yielding of Functionally Graded Long Tubes Under Thermal Loading;
(2006) Akiş,T.
The elastic behavior of a functionally graded non-uniform heat generating long tube is investigated analytically. The thermal conductivity and the modulus of elasticity of the tube material are assumed to vary radially in nonlinear forms. Making use of Tresca's yield criterion, the effect of grading parameters on the yielding behavior of the tube is investigated. It is observed that plastic flow may commence at the inner surface, at the outer surface or inside the tube depending on the functionally grading parameters.
