Structural Mechanics and Thermal Stresses

Energy Transformation Damping

G.S. Mulder[1]
[1]Leiden, The Netherlands

A model for material damping is presented in terms of internal friction and in terms of a variation of stiffness. In the latter case the idea is that the stiffness increases if elastic energy is stored and decreases if elastic energy is released. In case of a single mass spring system ... Mehr lesen

Simulation of a Modular Die Stamp for Micro Impact Extrusion

[1]Chair Micromanufacturing Technology, Faculty of Mechanical Engineering, Chemnitz University of Technology, Chemnitz, Germany
[2]Fraunhofer Institute for Machine Tools and Forming Technology, Chemnitz, Germany

Micro impact extrusion is investigated at Chemnitz University of Technology as a potential procedure for large area machining of micro cavities within the scope of the SFB/Transregio 39 PT-PIESA of the German Research Foundation. Applying impact extrusion micro forming is done by ... Mehr lesen

Punch Design for Uniaxial Forging Process of γ-TiAl Using COMSOL Multiphysics^®

R. Cagliero[1] and G. Maizza[1]
[1]Dipartimento di Scienza dei Materiali ed Ingegneria Chimica, Politecnico di Torino, Torino, Italy

The increasing demand for improved metallurgical products strongly motivates the optimization of manufacturing processes and design of γ-TiAl products. Among the large variety of available forming processes, cold closed-die forging is particularly suitable for producing net shape ... Mehr lesen

Effect of Local Deformation on the Emission Energy of Quantum Dots in a Flexible Tube

S. Kiravittaya[1], P. Cendula[2], A. Rastelli[2], and O. Schmidt[2]
[1]Max-Planck-Institut für Festkörperforschung, Stuttgart, Germany
[2]Institute for Integrative Nanosciences, Dresden, Germany

Strain induced by local deformation of a flexible micrometer-sized semiconductor tube is quantified by modeling a ball pressing on the tube wall. By changing the pressing condition, we are able to change the strain state of the tube wall incorporating self-assembled quantum dots (QDs) in ... Mehr lesen

Hybrid Finite Element-Finite Volume Algorithm for Solving Transient Multi-Scale Non-Linear Fluid-Structure Interaction during Operation of a Hydraulic Seal

A. Thatte, and R. Salant
Georgia Institute of Technology, Atlanta, GA, USA

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 ... Mehr lesen

Residual Stresses in a Panel Manufactured Using EBF3 Process

[1]Microelectronics and Micromechanics Department, Engineering school of ENSICAEN (Ecole National Superieure d'Ingénieurs de Caen), Caen, France
[2] Engineering Science and Mechanics Department, Virginia Polytechnic Institute and State University, Blacksburg, Virginia, USA
[3] Aerospace and Ocean Engineering Department, Virginia Polytechnic Institute and State University, Blacksburg, Virginia, USA

The residual stresses developed in a stiffened panel manufactured using Electron Beam Freeform Fabrication (EBF3) process were studied. EBF3 process is a layer additive process that can be used to build near-net shaped parts directly using computer controlled techniques, which can be ... Mehr lesen

Structural Mechanics of Cooling Catheters

M. Pavelchak, J. Urcinas, and T. Merrill
Rowan University, Glassboro, NJ, USA

This paper describes the use of structural mechanics capabilities within COMSOL to explore new cooling catheter designs. Cooling catheters may be used to save ischemic tissue resulting from strokes or heart attacks. Typical guide catheters use metallic braiding to ensure torsional ... Mehr lesen

Computational Analysis of the Mechanical and Thermal Stresses in a Thin Film PProDOT-Based Redox Capacitor
