An Investigation of the Brazier Effect of a Cylindrical Tube under Pure Elastic-Plastic Bending
The Brazier effect of originally straight cylindrical tubes under pure elastic-plastic bending is investigated by the deformation theory based on some deformation assumptions agreeing with numerous experiments. The expressions for bending moment and flattening ratio in terms of curvature are finally obtained
متن کاملElastic-Plastic Transition of Pressurized Functionally Graded Orthotropic Cylinder using Seth’s Transition Theory
In this paper the radial deformation and the corresponding stresses in a functionally graded orthotropic hollow cylinder with the variation in thickness and density according to power law and rotating about its axis under pressure is investigated by using Seth's transition theory. The material of the cylinder is assumed to be non-homogeneous and orthotropic. This theory helps to achieve better ...
متن کاملElastic-Plastic Analysis of Bending Moment – Axial Force Interaction in Metallic Beam of T-Section
This study derives kinematic admissible bending moment – axial force (M-P) interaction relations for mild steel by considering elastic-plastic idealizations. The interaction relations can predict strains, which is not possible in a rigid perfectly plastic idealization. The relations are obtained for all possible cases pertaining to the locations of neutral axis. One commercial rolled steel T-se...
متن کاملElastic-Plastic Transition in a Thin Rotating Disc with Inclusion
Stresses for the elastic-plastic transition and fully plastic state have been derived for a thin rotating disc with inclusion and results have been discussed numerically and depicted graphically. It has been observed that the rotating disc with inclusion and made of compressible material requires lesser angular speed to yield at the internal surface whereas it requires higher percentage increas...
متن کاملFractal Pattern Formation at Elastic-Plastic Transition in Heterogeneous Materials
Fractal patterns are observed in computational mechanics of elastic-plastic transitions in two models of linear elastic/perfectly plastic random heterogeneous materials: (1) a composite made of locally isotropic grains with weak random fluctuations in elastic moduli and/or yield limits and (2) a polycrystal made of randomly oriented anisotropic grains. In each case, the spatial assignment of ma...
