This thesis examines the forced, non-linear vibration of integral shroud turbine blades. The shroud of this type of blade is integral with the foil and root. During turbine operation small gaps are generally present between adjacent shrouds. If the amplitude of blade vibration is sufficient, adjacent shrouds will contact. This contact creates a dynamic non-linearity. A complete row of blades is considered in the analysis. The Ritz averaging method is used to develop an approximate displacement solution. Frequency response curves for a representative turbine blade are presented in the usual format.
