Description

It is demonstrated that by including the viscous force in the resistive MHD equations, a simple nonlinear theory can be constructed to account for the nonlinear effects on the linearly unstable tearing modes near the stability threshold. The method for carrying out the perturbational nonlinear analysis is described in detail. The essentials of this method are exhibited by working out the theory for simple sheet pinch geometry, calculating the effects of mode coupling of the second and zeroth harmonics on the evolution of the modes. 9 references
