Numerical analysis of reaction forces at the supports of sliding microwire

The reaction forces at the tungsten support probes of a platinum microwire are determined by numerical analysis for different push-pull sliding velocities and contact pressures. Finite Element Analysis (FEA) tool ANSYS Workbench is used to evaluate stresses, deformations microwire. nonlinear formulations implemented ensure that maintained with during motion, transfer frictional between surfaces without penetration separation. found independent velocity vary normal pressure. results in validated through experimental works. Due tiny size, nonlinearity contacts indeterminate supports criteria, it difficult determine conventional mechanics. method presented this paper can be other microstructures, validate results, as well total disturbance microstructures where relative motion exists; which important proper design failure MEMS devices microstructures.
