Analytical Solutions of Cracks Emanating from an Elliptic Hole in an Infinite Plate under Tension被引量：8
《Chinese Journal of Mechanical Engineering》2014年第5期1057-1063,共7页LIU Shuhong DUAN Shijie 
Supported by Hebei Provincial Natural Science Foundation of China(Grant No.A2011210033);Foundation of Hebei Education Department of China(Grant No.ZH2011116)
It is a common phenomenon that the cracks originating from a hole can cause structural damage in engineering.However,the fracture mechanics studies of hole edge crack problems are not sufficient.The problem of an elli...
