The paper presents the experimental and theoretical study for temperature distribution around the cooling pipes of an ice rink pad. The heat transfer in the skating rink track is nonstationary and phase changing. In case of skating rinks equipped with pipe registers, the temperature field during the ice formation process can’t be modeled by analytical methods. The experimental research was targeted on finding the temperatures in several points of the pad and also details on ice shape and quality around the pipes. The temperatures measured on the skating ring surface using thermocouples is impossible due to the larger diameter of the thermocouple bulb compared with the air-water surfaces thickness. For this reason we used to measure the temperature by thermography method, thus reducing the errors The experimental results were compared against the numerical modeling using finite elements.

Magnetic pulse process is used in the forming and welding processes. In order to predict the welding conditions, it is necessary to have an accurate modeling, which involves a coupling between magnetic and mechanical phenomena. In a first step, a numerical modeling of the magnetic field has been developed in the finite elements software ANSYS™, and the forces exerted on a tube have been predicted. The model has been validated by comparison with similar models. The influences of the different parameters have been studied. Then, the deformation of this tube has been predicted by a dynamical model in the finite elements software ABAQUS/Explicit™. As the tube shrinks, the mechanical and magnetic computings must be sequentially coupled in order to predict the forces exerted during the motion. Software MATLAB™ is used to couple the two models in the two softwares.

Concrete Ceiling

This paper deals with a modeling of the composite timber-concrete ceiling structure. In the analysis of the composite structure, there is the slip using the contact elements and volume finite elements considered. Numerical modeling is complemented by an analytical calculation. This article aims to determine the stiffness of a particular type of glued strip. Totally eight models of the composite timber-concrete structure have been studied.
