The uniaxial, biaxial, shear buckling and free vibration behaviors of FGP-GPLs plates were also examined by Yang et al. In addition, the static, free vibration and buckling of FGP-GPLs plates were also studied by Li et al. [27, 28] and by Senjanovic [29, 30] for the first time. In this study, free vibration analysis of the FGP plates reinforced by GPLs is studied in combi- nation of a generalized THSDT and IGA method.

Figure 4 shows significance of the correlation effects described by C R in the atomic vibration influencing on XAFS. In this work a new procedure for study of correlation effects of the atomic vibration of fcc crytals in XAFS has been developed. Derived expressions of the mentioned thermodynamic functions show their fundamental properties in temperature dependence.

Figure 1 Destroyed shaft line at high speed due to whirling vibration. The problems caused by whirling vibration are as the following:. o Complete shafting system destruction;. Shaft whirling vibration is closely related to the oil film pressure in shaft bearings. In the case of oil film stiffness variation, the vibration resonance changes.. This paper presents whirling vibration characteristics due to lubricating oil pressure variation in the diesel generator shafting system.

Therefore, the aim of the author is to determine these quantities from the results of torsional vibration measurements during the new built ship tests. and combined with the theoretical analysis we would generalize calculations of the above quantities. The paper presents a theoretical basis and algorithms of determining the torsional vibration damping coefficients of the engine structure, shaft material and hydrodynamic damping coefficient to propellers from results of vibration measurements.
