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...
Some test statistics of Kolmogorov type and Cramér-von Mises type based on projection pursuit technique are proposed for the testing problem of sphericity of a high-dimensional distribution. The limiting distribution...

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...
It is desirable to divide the frequency band into small bands over which an elliptical waveguide will possess an transverse cross section with an appropriate minor
The problem of determining the stress concentration caused by a hole in cylindrical shell is a basic one which, although very important in practice, has not yet been amenable to theoretical solution. gave a solution f...
