A Method of Solving Stress Intensity Factors of the Bent Crack in Three Points Bend Specimens
The unilateral straight crack in three points bend (TPB) specimens is in complex stress state when it is in the unsymmetrical position. It can propagate to become a bent crack when an alternating load is appli...

Fast oscillations and particle acceleration in the neutral sheet
This paper suggests that fast periodic oscillations in the neutral sheet occur after it is perturbed strongly. An analytic solution of the oscillation process, of which the period T is about 1 ms, is obtained on ...

The gradual and impulsive reconnection and the preheating of solar flares
We discuss the preheating phase of solar flares triggered by emerging magnetic flux. We consider the development of microinstabilities in the diffusion region during the emergence process and we propose four d...

Analysis of dipole and dipole array by a collocation technique with multipoint weighting
A collocation method with multipoint weighting is presented in this paper. It converges as rapidly as the Galerkin method but needs less computation effort. By means of the technique with Gauss points (superco...

On convergence of collocation technique
In this paper, the convergence rate at matching points of collocation technique is shown to beO(h 2), that is just the same as the global convergence rate of Galerkin’s method with triangular puls...
