摘要：
The single stress functions approach of Westergaard has often been conveniently used for a certain class of stress-prescribed crack problems. In the previous study, the Westergaard approach was successfully extended to displacement-prescribed crack problems. In this paper, the approach was further extended to the combined problem of displacement-prescribed cracks and stress-prescribed cracks. The method developed in the present paper simplifies the analysis of the mixed problem of interest. Several simple examples were discussed in detail to demonstrate the effectiveness of the method presented.
