A Consistent Environment for the Numerical Prediction of the Properties of Composite Materials
The current paper focuses on the creation of a consistent environment for the numerical prediction of the physical properties of polymer composite. A limitation factor for the successful simulation of composite processes is the correct estimation of the effective properties depending on ... 詳細を見る
A Study of Curved Flexures for MEMS
Large deflection actuators are becoming increasingly important for microsystems. Since actuation forces are usually small, large deflection actuators usually require flexures with low stiffness. Rectangular serpentine flexures are often used for such actuators due to their low stiffness ... 詳細を見る
High Coupling Factor Piezoelectric Materials for Bending Actuators: Analytical and Finite Elements Modeling Results
New giant piezoelectric factor materials such as PMN-PT and PZN-PT were researched during the last decade and are actually becoming commercially available. As they seem very attractive for actuator designs, we studied their potential in replacing PZT ceramics. In a first comparative ... 詳細を見る
Mobility of Catalytic Self-Propelled Nanorods Modeling with COMSOL Multiphysics®
A small particle or a nano-sized object placed in a liquid is subject to random collisions with solvent molecules. The resulting erratic movement of the object is known as Brownian motion, which, in nature, cannot be used to any practical advantage both in natural systems (such as ... 詳細を見る
Phasefield Modeling of Ferroelectric Materials
Outline of presentation: theory of phase-field modeling of ferroelectric materials parameter identification in free energy density finite element implementation: PDE form weak form periodic boundary conditions: electrical mechanical domain configurations intrinsic and extrinsic ... 詳細を見る
Oxidation of Metallic Nanoparticles
The oxidation behavior of metallic nanoparticles is investigated in respect to material parameters like Mott potential, defects on the microstructure and oxide volume increase per ionic defect. An emphasis is laid on magnetic nanoparticles where the degree of oxidation can be measured ... 詳細を見る
Simulation of Daisy Chain Flip-Chip Interconnections
Flip-chip interconnection technologies have been tested through the use of a test chip with embedded single-bump daisy chains. The Flip-Chip technologies are selected among Au bump Thermocompression (TC) with and without Nonconductive Adhesives (NCA) underfiller, anisotropic conductive ... 詳細を見る
Modelling of Micro/Macro Densification Phenomena of Cu Powder during Capacitor Discharge Sintering
Capacitor Discharge Sintering (CDS) is an ultrafast Electric Current Assisted Sintering method (u-ECAS) suited for electrically conductive powders. It is characterized by relatively short processing times (milliseconds range) and much lower sintering temperatures than the melting point ... 詳細を見る
Modelling of SiC Chemical Vapour Infiltration Process Assisted by Microwave Heating
The excessive presence of residual SiC matrix inter-fiber pores is often the main cause for the very poor mechanical strength and toughness of SiC/SiC composites manufactured by CVI (Chemical Vapour Infiltration) process. This work presents a micro/macro Microwaveassisted Chemical Vapour ... 詳細を見る
Dynamic Observation of Magnetic Particles in Continuous Flow Devices by Tunneling Magnetoresistance Sensors
Dynamic measurement of magnetic particles in continuous flow devices is made very difficult by the limitations imposed by the sensors themselves. Thus, certain sensor layouts are restricted to either number sensitive or spatial resolutive measurements of magnetic particles. We ... 詳細を見る
