... to solve the eigenfrequencies of the coupled system, a tracking solver method based on sliding mode control concept is used. An eight-blade system attached to a cantilever bar is used for an example to calculate a coupled vibration with a one-nodal diameter between the blade and shaft. References 1...

...T. Fett; D. Munz; G. Thun Bars loaded by opposite concentrated forces via rollers are appropriate test specimens for the determination of the fracture toughness, K Ic , and the crack resistance curve (R-curve) of ceramic materials. In this paper stress solutions for the proposed test specimens...
