Introduction. The transient nature of turbine blade radial deformation seriously influences the variation of High Pressure Turbine (HPT) Blade-Tip Radial Running Clearance (BTRRC) and the performance and reliability of gas turbine engines.Large radial deformation directly reduces BTRRC, resulting in the friction fault between blade tip and casing and even catastrophic failure under Cited by: springer, This book concerns the development of novel finite elements for the structural analysis of composite beams and blades.

(Prof.) J. Srinivas Department of Mechanical Engineering. Experience has shown that the structural dynamic behavior of a wind turbine system, good or bad, must always be dealt with by the design and operations teams. Through the use of known analysis methods, the effects of physical changes, controls, and subsystem features on the dynamic behavior of a new or existing wind turbine can be understood.
