In this paper, we study a one-dimensional quasi-static thermoelastic problem with unilateral contact with an elastic obstacle and heat flux through the boundary of contact. A finite element approximation is proposed and analyzed and some numerical experiments are performed.

A non-overlapping domain decomposition is applied to a multibody unilateral contact problem with given friction (Tresca’s model). Approximations are proposed on the basis of the primary variational formulation (in terms of displacements) and linear finite elements. For the discretized problem...

This paper deals with the full discretization of quasistatic 3D Signorini problems with local Coulomb friction and a coefficient of friction which may depend on the solution. After a time discretization we obtain a system of static contact problems with Coulomb friction. Each of these problems...

A discrete static contact problem with Coulomb friction is considered. The objective is to analyze non unique solutions. Since the model depends on parameters, we explore continuation (path-following) techniques for its numerical solution. In particular, we analyse a model with one and two...

A strong wind hit Aksaray province in Turkey on the March 12, 2013. In this natural disaster, two masonry minarets collapsed and one minaret slightly damaged. Fortunately, there was no human injured. In this paper, detailed information about the collapse mechanism of the minarets is given with...

The enzymatic biofuel cells (EBFCs) are considered as an attractive candidate for powering future implantable medical devices. In this study, a computational model of EBFCs based on three-dimensional (3-D) interdigitated microelectrode arrays was conducted. The main focus of this research is to...

This paper proposes a new multistage evacuated solar distillation system that was designed to increase the productivity and improve the efficiency of the simple solar still. The solar still works by virtue of the higher evaporation rate under vacuum conditions. A mathematical model for the...

Composite components of wind turbine blade are assembled with adhesive. In order to assess structural integrity of blades it is needed to investigate fracture of joints. In this study, finite element analysis based on fracture mechanics was conducted to characterize failure of adhesive joint for...

A new method for the hourly simulation of fields of long BHEs (borehole heat exchangers) is presented, in dimensionless form. The method considers also the internal structure of the BHE, with reference to double U-tube BHEs. The analytical expressions of new g-functions (time evolutions of the...

The necessity of an energy supplier was to solve an impact problem presented at the damper winding ring or short-circuit ring of a 625kVA generator and to redesign a fan for it. The principal restriction was the time. It should be done in 15 calendar days, working with drawings of the machine,...
