The augmented Lagrangian method consists of a standard Lagrange multiplier method augmented by a penalty term, penalising the constraint equations, and is well known as the basis for iterative algorithms for constrained optimisation problems. Its use as a stabilisation methods in computational mechanics has, however, only recently been appreciated. We first show how the method generates Galerkin/Least Squares type schemes for equality constraints and then how it can be extended to develop new stabilised methods for inequality constraints. Application to several different problems in computational mechanics is given. 2023-04-17T04:19:08Z 2023-04-17T04:19:08Z 2023 Book https://link.springer.com/article/10.1007/s11831-022-09878-6 https://dlib.phenikaa-uni.edu.vn/handle/PNK/7988 en application/pdf Springer
