The damage evolution and life prediction of cross-ply C/SiC ceramic-matrix composite (CMC) under cyclic-fatigue loading at room temperature and 800 °C in air have been investigated using damage parameters derived from fatigue hysteresis loops, i.e., fatigue hysteresis modulus and fatigue hysteresis loss energy. The experimental fatigue hysteresis modulus and fatigue hysteresis loss energy degra...

The hysteresis motor is so named because it is producing mechanical torque utilizing the phenomenon of hysteresis. The rotor of a hysteresis motor is a cylindrical tube of high hysteresis loss permanent magnet material without windings or slots. This paper presents the design of a hysteresis permanent magnet motor using the finite element method. The rotor of the machine consists of 36% Cobalt ...

Pulse Width Modulated (PWM) Rectifiers offer a promising and high end performance for the ac to dc conversion needs of the industry, customer and power grid sectors. This paper presents a reduced switching loss algorithm applied to a hysteresis current controlled PWM rectifier. This acts as an ac to dc boost converter with near unity power factor at the grid side along with regulated and ripple...

— In electromagnetic applications, hysteresis phenomena in magnetic materials are responsible of considerable causes of losses especially in transformer modelling cases. In specific case, such as current sensor, the output signal can be modified because of this loss. The paper presents the implementation proceeding used for some hysteresis material models and how they are applied in a sensor st...

Wear is an important issue in hip implants. Excessive wear can lead to toxicity and other implant associated medical issues such as patient discomfort and decreased mobility. Since implant wear is result of contact between surfaces of femoral head and acetabulum implant, it is important to establish a model that can address implant surface roughness interaction. A statistical contact model is d...
