A Study on Fracture Behavior of Brazed Multicrystalline CBN Abrasive Grains During Grinding
This paper analyses the fracture behavior of the brazed BCBN grain by comparison with brazed PCBN grain through grinding test of Nickel-based superalloy. The self-sharpening effect is created by timing micro-fracture behavior for BCBN abrasive grains, but by macro-fracture behavior for PCBN abrasive grains. During grinding with brazed BCBN abrasive grains, the material is removed together with ...
متن کاملFrequency Selectable Induction Heating Targets
This paper examines a scheme for developing frequency selectable induction heating targets for stimulating temperature sensitive polymer actuators. “Frequency selectable” implies that each target has a frequency at which it heats preferentially compared to other remaining targets. Single-turn conductors whose critical dimensions are small compared to their associated skin depth (over the freque...
متن کاملResidual Stresses Measurement of a Quenched Cylinder using Slitting Method
Residual Stress measurement has gained interests among researchers for many years due to its great influence on the structural integrity. Slitting method is one of the destructive techniques that relies on the introduction of an increasing cut to a part containing residual stresses. Similar to all other mechanical strain relief techniques, slitting also suffers from its shortcomings during the ...
متن کاملA New High Frequency Grid Impedance Estimation Technique for the Frequency Range of 2 to150 kHz
Grid impedance estimation is used in many power system applications such as grid connected renewable energy systems and power quality analysis of smart grids. The grid impedance estimation techniques based on signal injection uses Ohm’s law for the estimation. In these methods, one or several signal(s) is (are) injected to Point of Common Coupling (PCC). Then the current through and voltage of ...
متن کاملFrequency Response Analysis of a Capacitive Micro-beam Resonator Considering Residual and Axial Stresses and Temperature Changes Effects
This paper presents a study on the frequency response of a capacitive micro-beam resonator under various applied stresses. The governing equation whose solution holds the answer to all our questions about the mechanical behavior is the nonlinear electrostatic equation. Due to the nonlinearity and complexity of the derived equation analytical solution are not generally available; therefore, the ...
