✦ Synopsis

This work presents an assumed hybrid displacement finite element model to deal with an axisymmetric cracked solid subjected to static as well as dynamic torsional loadings. A ring type hybrid singular crack element embedded with correct Williams' singularities is devised to analyze the region near the crack-front. The static and dynamic mode III stress intensity factors K,ll for the cracked cylinder can be obtained directly. The need for using a hybrid singular crack element is displayed. The numerical examples presented include (I) static analysis, (2) torsional vibration problem and (3) dynamic analysis. Good correlations between the computed results and available solutions in the literature show the accuracy and high efficiency of the present work. The mistake in Dimarogonas and Massouros's work for torsional vibration analysis is also corrected. * 4 + axpZ cos 2 + CXyp-"? cos T .
