The result shows: the local residual tensile stress and cyclic compressive loading thrust fatigue crack initiation and propagation in the size of compressive plastic zone.
The initiation of Wuhan Maple Leaf Education Park is a new important action of Wuhan Donghu Development Zone in importing superior education resources to support China optics valley construction.
武汉枫叶教育园区的奠基是武汉东湖新技术开发区引进优质教育资源服务中国光谷建设的又一重要举措。
