Elastoplastic Models of the Interaction between Active Fronts of the Southern Alps and Dinarides (NE Italy and NW Slovenia)
We use GPS measurements and Finite Element analysis to investigate strain accumulation in the interaction between active fronts of the Southern Alps and Dinarides at the northern edge of the Adriatic micro-plate. We develop a three dimensional model of the area taking into account the ... Read More
On the Numerical Modeling of Elastic Resonant Acoustic Scatterers
The elastic and geometrical properties of Low Density Polyethylene (LDPE) foam are used in this paper to improve the attenuation properties of periodic arrangements of acoustic scatterers known as Sonic Crystals (SCs). A specific recycled profile of LDPE foam is used as elastic-acoustic ... Read More
Finite Element Model of a Complex Glass Forming Process as a Tool for Control Optimization
This paper addresses the modeling of a complex glass forming process as an example of a complex, nonlinear distributed parameter system. The system is modeled by a fluid dynamics approach, which means that the forming is regarded as a fluid with free surfaces. Here, the coupling of the ... Read More
Designing Polymer Thick Film Intracranial Electrodes for use in Intra-Operative MRI Setting.
A new type of MRI compatible intracranial electrode based on Polymer Thick Film (PTF) is presented and studied using COMSOL Multiphysics. The geometry considered was a two-dimensional cross section cut of 5 mm thick electrodes with 5 cm leads on top of a 2×10 cm slab representing ... Read More
A Preliminary Approach to the Neutronics of the Molten Salt Reactor by Means of COMSOL Multiphysics®
The Molten Salt Reactor (MSR), proposed along with other five innovative concepts of fission nuclear reactor by the Generation IV International Forum (GIF-IV), represents a challenging task from the modeling perspective because of the strong coupling between neutronics and thermo ... Read More
Analysis of Electromagnetic Propagation for Evaluating the Dimensions of a Large Lossy Medium
In this paper the propagation of a plane wave in a large lossy medium is presented. The investigated geometry consists in a wedgeshaped lossy dielectric embedded in a lossy material with different electromagnetic properties. The aim of the study is to determine the feasibility of a radar ... Read More
Fatigue Damage Evaluation on Mechanical Components under Multiaxial Loadings
This paper is concerned with the fatigue behavior of complex, three-dimensional, stress concentrations under multiaxial loadings. Starting from the stress field obtained from a linear elastic analysis and taking advantage of the so-called implicit gradient approximation, an effective ... Read More
Definition of Optimization Problem for Electromagnetic Linear Actuator
In this paper a poly-optimization of the design of the electromechanical actuator is presented. The shape of the actuator is defined by the decision variables. The number of decision variables under consideration is up to ten but in the next step while the multi-coils system will be ... Read More
The Full-System Approach for Elastohydrodynamic Lubrication
A ball is in contact with a plane, and a lubricant separates the two surfaces to decrease friction during their relative motion. To avoid wear, the lubricant film thickness should be higher than the surface roughness. The goal of this paper is to show how it is possible to solve ... Read More
Boundary conditions in multiphase, porous media, transport models of thermal processes with rapid evaporation
In modeling of thermal processing of biological materials with rapid evaporation, it is critical to provide boundary conditions consistent with the phenomena happening at the surface to accurately predict spatial temperature and moisture content for quality and safety assurance. Boundary ... Read More
