title = "On the implementation of Augmented Lagrangian Method in the 2D Discontinuous Deformation Analysis",
abstract = "The penalty method employed by the Discontinuous Deformation Analysis (DDA) is easy to be implemented in the program but the contact constraint is only approximately satisfied. The penetrations between contacting blocks are unavoidable even if the penalty value is very large. To improve the contact precision, an Augmented Lagrangian Method (ALM) is introduced in this paper, which can make use of advantages of both the Lagrange multiplier method and the penalty method. Examples are provided to show the computational efficiency and contact precision of the ALM enhanced DDA.",
