The author establishes a finite element solver algorithm of optimal speed for a class of quasi-linear equations with large stiffness variations and oscillations. In particular, the algorithm can successfully handle soft inclusions of negative stiffness. Besides the convergence analysis, large number of numerical examples are presented.
