Let $G$ be a generalized Baumslag-Solitar group and $\mathcal{C}$ class of groups containing at least one non-unit closed under taking subgroups, extensions, Cartesian products the form $\prod_{y \in Y}X_{y}$, where $X, Y \mathcal{C}$ $X_{y}$ is an isomorphic copy $X$ for every $y Y$. We give criterion to residually $\mathcal{C}$-group provided consists only periodic groups. also prove that tor...

The residual soil is one of the major soils in peninsular region Malaysia. Because this, engineering activities can employ this kind building industry, such as retaining walls and high-rise building. Yet, because it structurally complicated has substantial weathering most locations, often brings heterogeneities, which lead to failure a structure. Finding value shear strength parameters geotechn...

In this paper, the effect of autofrettage process parameters on the ultimate pressure that functionally graded spherical vessel can tolerate are investigated. FGM properties and autofrettage pressure are considered as important parameters. Assumptions are variation of properties of FGM in radial direction, the residual stress in the absence of Bauschinger effect with the operation of variable m...

Recently, some fluid or pour resins have been introduced to simplify the processing of dentures. However, because of the presence of relatively high residual monomer, the mechanical properties of these resins are inferior to those of heat cured resins.1,2) The purpose of the present investigation is to measure the quantities of residual monomer and to investigate the effect of the residual mono...

In the present article a numerical procedure is developed for dynamic analysis of single and double autofrettage of thick–walled FG cylinders under transient loading. The governing differential equations are discretized and presented in explicit Lagrangian formalism. The explicit transient solution of discrete equations are obtained on the meshed region and results for stress and strain distrib...
