A constitutive model based on the evolution and coalescence of elliptical micro-cracks for quasi-brittle materials被引量:2
《Chinese Science Bulletin》2012年第28期3773-3781,共9页NING JianGuo REN HuiLan FANG MinJie 
supported by the National Natural Science Foundation of China (11032002 and 11172045)
Damage and failure of quasi-brittle materials are caused by the evolution and coalescence of micro-cracks.To solve the problem of elliptical micro-crack growth at the elastic deformation stage,a method of complex pote...

DOES THE PULSAR BEAM HAVE AN ELLIPTICAL CROSS SECTION?
《Chinese Science Bulletin》1989年第13期1116-1120,共5页吴鑫基 沈志强 
Project supported by the National Natural Science Foundation of China
According to the RC model proposed by Radhakrishnan and Cooke in 1969, the pulsar beam is a cone of circular cross section. However, Jones first put forward a proposal that pulsar beams may be elongated in the latitud...
