Dynamic fracture behaviour of crack curving in bent beams has beeninvestigated.In order to understand the propagation mechanism of such cracks underimpact,an ex
The perturbation of symmetries of the free Birkhoff system undersmall excitation is discussed.The concept of high-order adiabatic invariant is pre-sented,and th
A new method is developed for three-dimensional stress analysis oflaminated piezoelectric cylindrical shell with simple support. The shell can be sub-jected to
In the present paper,the algorithm of Binary Image Cross-Correlation(BICC)was developed to measure the unsteady flow field.A vortexflow field was used to test t
By the aid of an idea of the weighted ENO schemes, some weight-type high-resolution difference schemes with different orders of accuracy are presentedin this pa
On the basis of Betti’s theorem,the constitutive relation of multi-crack rockmass which considers the effect of crack-closure is developed in this paper.Meanwh
