Determining Elastic-Plastic Material Properties Using Instrumented Indentation Test and Finite Element Simulation

Promer D.R., Najafabadi Z.S., Kim J., Kujawski D., Western Michigan University, US

A new technique that can determine the elastic-plastic properties of metallic materials using the instrumented indentation test and finite element simulation is developed. This non-destructive technique can be applied to additively manufactured and/or surface treated [...]

Modification of rubber surface with hydrogenated diamond-like carbon thin films

Pei Y.T., Bui X.L., De Hosson J.Th.M., University of Groningen, NL

Thin films of hydrogenated diamond-like carbon (DLC) have been deposited on hydrogenated nitrile butadiene rubber (HNBR) for reduction of friction and enhancement of wear resistance of dynamic rubber seals, by sputtering graphite targets in C2H2/Ar [...]

Laser Induced Surface Modification of Ceramic Substrates for Thermal and Electric Lines in Microsystems: Modeling Compared to Experiment

Gruhn H., Heidinger R., Rohde M., Rüdinger S., Schneider J., Zum Gahr K.-H., Forschungszentrum Karlsruhe, DE

Laser induced surface modification has been used to fabricate conducting paths in ceramic substrates. For the purpose of process simulation and prediction of process parameters a finite element model has been developed to simulate the [...]

MEMS Design Optimization Using Coupled FEM and Electrical Circuit Simulation

Krassow H., Zabala M., Götz A., Cané C., Centro Nacional de Microelectronica, ES

The FEM (Finite Element Method) package ANSYS includin`, the CFD (Computational Fluid Dynamics) module FLOTRAN was coupled with the electrical network simulator HSPICE for the comprehensive design of microsystems. The coupling permits the simultaneous optimization [...]

Analysis and Characterization of Laterally Induced Electrostatic Repulsive Forces

Lee K.B., Cho Y-H, Korea Advanced Institute of Science and Technology, KR

We analyze and characterize the laterally induced electrostatic repulsive force generated by the in-plane asymmetry of electrostatic field. Basic concept of the electrostatic repulsive actuation is presented. Fundamental nature of the repulsive force has been [...]
