A neutrino oscillation experiment aims to the observation of the transformation of a neutrino of a given flavour into a neutrino of a different flavour. A beam of neutrinos is produced through the decay of charged pions which in turn are produced in the collision of high energy accelerated protons impinging on a thick target. A series of magnetic horns is used to focus charged particles produced ...

Turgor pressure loss and pectin degradation result in texture loss during cooking of plant based materials. To simulate texture loss, a simultaneous heat and moisture transfer, pectin degradation in the cell wall material and solid mechanical model was developed at the microscale using finite elements to predict the homogenized Young’s Modulus of the carrot tissue during heating. The model ...
Defining the stress fields for the safety design of the LBT adaptive secondary mirror - FEMLAB/MATLAB set of functions to define and compute shell overstressing
Del Vecchio C., Busoni L., Riccardi, A.
This paper presents the most important safety issues of the thin glass shell of the LBT Adaptive Secondary Mirror. Two overstressing conditions are investigated: the condition in which the mirror shell is passively supported and the condition of a failure of the control system governing the actuator forces. The two stress analyses determine the portion of the mirror which may exceed a certain ...

This paper deal of the forming process applied to the thermoplastic composites. A new thermoforming process that uses rubber particles collection as flexible mould was presented and numerically modeled. A characterization of the rubber in particles form was previously performed to value the material parameters in the user-defined hyperelastic constitutive laws employed in the FEM (Finite Element ...

The present work aims to describe the behavior of the interface using the method of load transfer between fiber and matrix in a composite material. Our contribution was first to simulate the mechanical behavior of a composite, for a given radius of the fiber was able to automate the result for different rays thus different proportions of the reinforcement, the simulation was done with software ...

Many optoelectronic devices utilize a heterojunction of a pair semiconducting materials including high-efficiency MEMS devices, solar cells, LEDs, and VCSELs. One fabrication technique which achieves such a device is direct wafer fusion. To optimize the process, COMSOL Multiphysics 4.0 was used to test various geometric configurations of the fixture. 2D and 3D models were created in order ...

Hot Isostatic Pressing (HIP) has been selected as a means of treating calcined high level waste (HLW). The process combines high temperature and pressure to densify the HLW in to a mineral similar to the geologic formulation of granite. This study uses COMSOL to predict densification and shape deformation of a stainless steel can filled with HLW. Two approaches were used to model densification ...

Utilization of bioreactors to regenerate tissues outside the body has been intensely investigated in functional tissue engineering. Various studies have been performed using computational fluid dynamics (CFD) to understand fluid flow within bioreactors while assuming porous scaffold as a rigid structure. However, the physical and mechanical properties of most tissue engineering scaffolds suggest ...
Hybrid Finite Element-Finite Volume Algorithm for Solving Transient Multi-Scale Non-Linear Fluid-Structure Interaction during Operation of a Hydraulic Seal

This paper presents a hybrid finite element – finite volume algorithm for solving multi-scale fluid-structure interaction during transient operation of a hydraulic rod seal. The elasto-hydrodynamic model consists of several micro-scale and macro-scale analyses types, all incorporated in a single hybrid iterative computational framework to solve these highly coupled nonlinear multiphysics ...

The two wooden cabinets of Jan van Mekeren that are located in Amerongen Castle show comparable wood damage; in particular large cracks in the cabinet doors are clearly noticeable. It is assumed that these cracks were caused by bad indoor climate conditions in the castle. Combined computational modelling of the indoor climate conditions in the castle and the hygroscopic and mechanical ...
