The changing of wave structure in excitable media in external field is studied and the curvature relation of wave front is analyzed. Under external stimulus the
A so-called “local probabilistic Paris relation method” was presented for measuring the random thresholds of long fatigue crack propagation. A check was made
In order to obtain the failure probability of the implicit limit state equation accurately, advanced mean value second order (AMVSO) method was presented, and a
An improved implementation of Distributed Lagrange multiplier/fictitious domain method was presented and used to simulate the interactions between two circular
The vortex-induced nonlinear vibration of casing pipes in the deep water was studied considering the loads of current and combined wave-current. The vortex-indu
In respect of variable coefficient differential equations, the equations of coefficient function approximation were more accurate than the coefficient to be fro
A universal numerical approach for nonlinear mathematic programming problems is presented with an application of ratios of first-order differentials/differences
