A penalized viscoplastic contact problem with unilateral constraints
Abstract In this paper we study a mathematical model which describes the quasistatic contact between a viscoplastic body and a…
Read MoreOn the behaviour of the solution to a viscoplastic contact problem
Abstract The present paper represents a continuation of [2]. There, a quasistatic contact problem for viscoplastic materials was considered, in…
Read MoreAnalysis of a history-dependent frictionless contact problem
Abstract We consider a mathematical model which describes the quasistatic contact between a viscoelastic body and an obstacle, the so-called…

Abstract The reanalysis of the timing data of the binary system ER Vulpeculae revealed the superposition of a relatively slow…
Read MoreApplication of the Jacobi-Davidson method to accurate analysis of singular linear hydrodynamic stability problems
Abstract The aim of this paper is to show that the Jacobi–Davidson (JD) method is an accurate and robust method…
Read MoreLaguerre collocation solutions to boundary layer type problems
Abstract In this paper a Laguerre collocation type method based on usual Laguerre functions is designed in order to solve…
Read MoreA mixed finite element discretization scheme for a concrete carbonation model with concentration-dependent porosity
Abstract We investigate a prototypical reaction–diffusion-flow problem in saturated/unsaturated porous media. The special features of our problem are twofold: the reaction…
Read MoreA coupled finite element–global random walk approach to advection-dominated transport in porous media with random hydraulic conductivity
Abstract Solute transport through heterogeneous porous media considered in environmental and industrial problems is often characterized by high Péclet numbers.…
Read MoreNumerical demodulation of a Gaussian white noise modulated in amplitude by a deterministic volatility
Abstract The Gaussian white noise modulated in amplitude is defined as the product of a Gaussian white noise and a…
