How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
The author would like to bring attention to some incorrect relations and statements in a recently published article in this journal.
The instability strain of material considering the effect of elastic deformation is presented using the Ramberg-Osgood stress-strain relation. The relationship between the instability stress and the instability strain under the plastic incompressibility is assumed, where v is the Poisson ratio and is the elasticity modulus. Some of the numerical an...
In this article, the large deflections of a thin cantilever beam under an end moment is considered. The material behavior of the beam is assumed to be nonlinear bimodulus. The aim of this study is to investigate the effect of bimodulus behavior on the horizontal and vertical deflections at the free end. The numerical results obtained are tabulated....
The subject of investigation is a linear hardening annular disk of variable thickness subjected to external pressure. The variation of thickness is considered for two different cases: (1) h = ho (1 − tr)k and (2) h = ho (1 − trk), where h0, t and k are real constants. The analysis is based on Tresca's yield condition and its associated flow rule. T...
We study the elastic-plastic stress distribution in a rotating hyperbolic annular disk mounted on a circular rigid shaft. The presented exact solution is based on the usual assumptions of plane stress, Tresca’s yield condition, its associated flow rule and linear strain hardening material behaviour. According to the present analysis, the plastic co...
