In this paper, based on the theory of elastic structure analysis, considering rotational softening and centrifugal stiffening blade, dynamic model fir-tree rotating blade macroslip hysteresis dry friction contact surface tenon are established. Based mechanics, pressure distribution is innovatively established relationship between fit clearance has been derived. After discretized by finite eleme...

The aim of the present article is to demonstrate challenges connected with translation children’s poetry, and offer a qualitative analysis different strategies employed in two English translations Polish poem for children “Lokomotywa” by Julian Tuwim. based on proposed Lawrence Venuti Peter Newmark. It focuses linguistic cultural differences between English, examines choices made translators, i...

In this article, the residual vibration of a simply supported beam with moving mass is studied. The moves from starting point to an end on trapezoidal velocity profile having accelerating, constant and decelerating time intervals. mid-point after stops analyzed. mathematical model system developed using finite element (FE) theory. Newmark method used for solution FE dependent matrices because m...

Abstract Vibrational characteristics of a sandwich beam in thermal environments subjected to blast pressure are investigated this paper. The is composed two isotropic skins and an open-cell metal foam core with either uniform or symmetric distribution internal pores. loading modelled by Friedlander’s equation. A two-unknown higher-order theory combined Hamilton’s principle used establish the go...

Many innovative floating offshore structures have been proposed for cost effectiveness of oil and gas exploration and production in water depths exceeding one thousand meters in recent years. One such type of platform is the offshore floating Spar platform. The Spar platform is modelled as a rigid body with six degrees-of-freedom, connected to the sea floor by multicomponent catenary mooring li...

Protected areas are commonly assumed to (and most do) harbour higher densities of wildlife than adjacent, humanmodified landscapes (Woodroffe & Ginsberg, 1998; Melville & Bothma, 2006; Gaston et al., 2008; Newmark, 2008; Kiner et al., 2009). In north-central Namibia, farmers believed that leopard (Panthera pardus) densities were growing on farmland areas adjacent to Waterberg Plateau Park and t...

Large amplitude flexural vibration characteristics of functionally graded material plates under aerodynamic load are investigated here using the finite element approach. Material properties of the plate are assumed to be graded in the thickness direction according to a simple power-law distribution and the effective material properties are evaluated based on the rule of mixture. The formulation...

The present work is an extension of the previous one [1] which dealt with error analysis of a finite volume scheme of first order (both in time and space) for second order hyperbolic equations on general nonconforming multidimensional spatial meshes introduced recently in [4]. The aim of this contribution is to get some second–order time accurate schemes for a finite volume method for second or...

This paper is intended to be a first step towards the continuous dependence of dynamical contact problems on the initial data as well as the uniqueness of a solution. Moreover, it provides the basis for a proof of the convergence of popular time integration schemes as the Newmark method. We study a frictionless dynamical contact problem between both linearly elastic and viscoelastic bodies whic...

Steel-concrete composite girder bridges, in essence, are thin-walled structures, the dynamic responses of which will be greater than those a typical Euler–Bernoulli beam under train-bridge interaction because shear lag and interface slip. Thus, this study, analysis model train-composite box bridge-multiple tuned mass damper (MTMD) coupling system is proposed, with derived equations time-varying...
