Structural Mechanics and Thermal Stressesx

Structural Durability Analysis of Powertrain Mounting Bracket

Sameer Kolte[1], David Neihguk[1], Abhinav Prasad[1]
[1]Mahindra and Mahindra Ltd., Vehicle Integration COE, Mahindra Research Valley, Mahindra World City, Chengalpattu, Tamil Nadu, India

Structural analysis is performed to check the durability of Engine mounts for a given load and support conditions. The engine mount bracket is subjected to loads primarily due to weight of the powertrain and the unbalanced torque. In this analysis, the component is optimized such that ... Mehr lesen

High Curvature Bending of Ultra-Thin Chips and Chip-on-Foil Assemblies

D. van den Ende[1]
[1]Holst Centre / TNO, Eindhoven, The Netherlands

Ultra-thin chips of less than 20µm become flexible, allowing integration of silicon IC technology with highly flexible electronics. This combination allows for highly intelligent products of unprecedented thinness, flexibility and cost. Examples include sensor systems integrated into ... Mehr lesen

Particle Focusing Optimization and Stress Analysis of a Magnetic Horn

S. di Luise[1], A. Rubbia[2]
[1]Swiss Federal Institute of Technology, ETH, Zurich, Switzerland and CERN European Organization for Nuclear Research, Geneva, Switzerland
[2]Swiss Federal Institute of Technology, ETH, Zurich, Switzerland

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 ... Mehr lesen

Fracture on Circuit Board Internal Layers Due to Thermal Stress on Soldered Pins

F. Figueroa[1], P. Aguirre[1]
[1]Sensor Technik Wiedemann GmbH, Kaufbeuren, Germany

Circuit board failures are often ignored because they could be impreceptible. This simulation examines how internal layers around a soldered pin via subject to temperature changes during the soldering process are affected, show the forces involved and determine breaking points. A 2D ... Mehr lesen

Residual Stresses and Failure Probability of Solid Oxide Fuel Cells Due to the Sintering Process

F. Greco[1], J. van Herle[1], A. Nakajo[1]
[1]FUELMAT Group, Institute of Mechanical Engineering, Ecole Polytechnique Fédérale de Lausanne, Lausanne, Switzerland

A solid oxide fuel cell (SOFC) is composed of four layers (anode, electrolyte compatibility layer and cathode) of different ceramic materials. The anode layer is produced by tape casting, the remaining layers are deposited by screen-printing. The layers are sintered together at high ... Mehr lesen

Simulation of Wear using LiveLink™ for MATLAB®

D. Sutton[1]
[1]National Centre for Advanced Tribology at Southampton, University of Southampton, Southampton, United Kingdom

An incremental wear model has been developed using COMSOL Multiphysics® with MATLAB® to predict the evolution of component geometry as a result of wear. Whilst Archard’s wear law is a well-known empirical model for the prediction of wear volume, the design engineer is interested in ... Mehr lesen

Structural Mechanics for Real Geometry of Basalt Woven Composites

J. Salacova[1]
[1]Technical university of Liberec, Department of Material Engineering, Liberec, Czech Republic

Woven composites with basalt reinforcement plain 1x1 are examined to define structural mechanics. Woven composites were created by the prepreg technology, 8 layers of plain-weave basalt fabrics were saturated by the precursor, polysiloxane matrix Lukosil®, and joint pressed during ... Mehr lesen

Parametric Study of Polyimide - Lead Zirconate Titanate Thin Film Cantilevers for Transducer Applications

A. Arevalo[1], I.G. Foulds[1]
[1]King Abdullah University of Science and Technology, Thuwal, Kingdom of Saudi Arabia

The simulation of the piezoelectric actuation of the micro-cantilever is presented. Lead Zirconate Titanate (PZT) was chosen for the device fabrication design, due to its thin film processing flexibility. Four layers compose the cantilever structures presented in this work: PZT ... Mehr lesen

A Concrete Arch Dam under Seismic Loading Conditions

A. Frigerio[1], G. Mazzà[1]
[1]RSE S.p.A., Milan, Italy

A new regulation for the safety assessment of dams has just been developed in Italy and its approval process is still in progress. As a matter of fact the behaviour of dams under seismic loading conditions is deemed of actual interest due to the recent seismic events occurred. In ... Mehr lesen

High-Intensity Piezo-Ceramic Ultrasonic Transducer with Mechanical Amplifier and Radiation Plate

A. van Wijhe[1], W. de Jong[1]
[1]Process & Energy, 3mE, TU Delft, The Netherlands

A COMSOL Multiphysics® model was made to design a mechanical amplifier and radiation plate for the emission of high intensity 40.5 kHz ultrasound to air by means of a Langevin type transducer usually applied in cleaning baths for example. In this work, ultrasonic irradiation is aimed at ... Mehr lesen
