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...

Peridynamics is a nonlocal theory for dynamic fracture analysis consisting in second order time partial integro-differential equation. In this paper, we consider nonlinear model of peridynamics two-dimensional spatial domain. We implement spectral method the space discretization based on Fourier expansion solution while Newmark-? marching. This computational approach takes advantages from convo...
