Arc-Length method newton-rapson 方法实现相对简单,收敛速度也很快,但是不能处理涉及软化、分岔以及失稳的问题(会出现奇异的切线刚度),应该使用弧长法(arc-length method)。 牛顿法不能处理失稳类问题的原因是它只加载不卸载,在弧长法中,载荷因子 λ 是待求变量,能增也能减。 假设(u0,λ0) 是平衡解,假定增量...
Next, for the numerical solution of the problem the combination of Crank–Nicolson Lagrange–Galerkin with the augmented Lagrangian active set method is described. Finally, some numerical examples illustrate the theoretical properties of the optimal redeeming boundary previously stated in the literature. ...

This paper develops a probabilistic numerical method for solution of partial differential equations (PDEs) and studies application of that method to PDE-constrained inverse problems. This approach enables the solution of challenging inverse problems whilst accounting, in a statistically principled way, for...
