โœฆ Synopsis

Sunmaary--This study is concerned with the development of a generalized theoretical method for the treatment of the dynamic interaction between a main crack and an arbitrarily located and oriented microdefect near its tip under antiplane loading. The steady-state theoretical solution of this class of problems is formulated using integral transform techniques and an appropriate self-consistent iterative technique. The resulting singular integral equations are solved using Chebyshev polynomials to provide the dynamic stress intensity factors at the main crack as a function of frequency. Numerical examples are provided to show the effect of a main crack interacting with a microcrack, a hole or an inhomogeneity. Specifically, the effect of the location and material properties of the microdefects and the frequency of the incident wave upon the dynamic stress intensity factors of the main crack is examined.

A ยฎnite element technique is used to investigate the free-vibration characteristics of rotating laminated composite blades. The structure is discretized using a multilayered degenerated-solid shell element. Because of the geometry and the loading, a geometrically non-linear analysis is required. The
