摘要：

This paper deals with the development and application of a special crack-tip finite element to obtain the bending and shear intensity factors for thin elastic plates containing cracks. The bending and shear intensity factors are then used to compute the Strain Energy Density Factor and the direction of crack initiation. The solution procedure is illustrated through several numerical examples. The problem of an axial flow compressor blade containing a crack is solved using a combination of special crack tip plate bending and plane stress elements. © 1979.
