This paper documents the experimental validation of an active control approach for mitigating chatter in milling. To the authors knowledge, this is the first successful hardware demonstration of this approach. This approach is very different from man

Power conversion electronics in military vehicles and aircraft are currently experiencing high temperatures and future generations will see these temperatures rise even higher. The high temperatures arise not only from the environment but also from h

Compressive prestress effects on the electrical and mechanical properties of relaxor ferroelectric materials were studied as a function of temperature for several formulations of Pb(Mg1/3Nb2/3)O3-PbTiO3-BaTiO3 (PMN-PT-BT) ceramics. Experimentally mea

The quasi-static coupling coefficients, k/sub 13/ and k/sub 33/, for electrostrictive ceramics are computed analytically. The calculation is based on a three-dimensional constitutive relation that models both electrostriction and nonlinear dielectric
