In this study, magneto-rheological elastomer (MRE) composite beams made of Barium hexaferrite (BaM) and Iron (Fe) powders combined with a highly-compliant matrix material were simulated using COMSOL\'s Solid Mechanics and AC/DC modules. The goal of the work was to develop models capable of predicting the actuation behavior of hard- and soft-magnetic MREs. This work simulates the bending of ...

Simulation models for steady state thermal hydraulics analyses of ORNL’s HFIR have been developed using COMSOL. A single fuel plate and coolant channel of each type of HFIR fuel element was modeled in three dimensions. The standard k-? turbulence model was used in simulating turbulent flow with conjugate heat transfer. The COMSOL models were developed to be fully parameterized to allow ...

Microwave drying of foodstuffs is a complex interplay of mass, momentum, and energy transport coupled with large deformation of the solid. To be able to better understand the microwave drying process, a fundamentals-based three dimensional (3D) multiphase porous media based model is developed to simulate the microwave drying process. An elaborate experimental system comprising of infrared ...

Instrumented indentation is increasingly used as an alternative non-destructive test method to measure mechanical properties of small volumes of materials. In this work, the instrumented indentation test is applied as a non-destructive method to assess the mechanical properties of TiAl components during the setup of a real production process. This study is a preliminary contribution devoted to ...

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 ...
Viscoelastic Mechanical Analysis for High Temperature Process of a Soda-Lime Glass Using COMSOL Multiphysics
Material and Production Engineering Department, University of Naples “Federico II”, Naples, Italy
Glasses are widely used in the modern industry. For high temperature the glass behaves very much like a Newtonian liquid with temperature-dependent viscosity. The goal of this study is to set a numerical procedure in order to study the glass forming process of soda-lime glasses used in the automotive field by means numerical simulations.

Groundwater-bearing geological layers respond to and modify the surface expressions of magmatic activity, and they can also become agents of volcanic unrest themselves. Interpretations of unrest signals as groundwater responses to changes in the magmatic system can be found for many volcanoes and include a wide range of phenomena and suggested processes to explain them (e.g., Newhall et al., ...

Introduction: Solver section of FEA plays a very important role; it takes the input from the preprocessor and solves millions of equations using numerical methods. Capability of any analysis tools can be measured based on the solver. Understanding the nature and operation of various structural solid mechanics solvers is the interest of the present study. Results: Contact pressure is ...

The analysis performed is categorized into two levels: 1. The thermal stress distribution on the sensing part with the variation in the substrate three glass material with appropriate dimensions and exposures. The reason behind this consideration of different materials is test the compatibility with the crystal. This variation in substrate material and its material properties shows which is ...

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 ...
