A large deformation frictional contact formulation using NURBS‐based isogeometric analysis (2011, background): “[27], integration is here carried out without segmentation of the contact surfaces to avoid the associated computational cost.”
A mortar formulation for 3D large deformation contact using NURBS-based isogeometric analysis and the augmented Lagrangian method (2012, methodology): “Like in Tur et al. [ 39 ], integration is here carried out without segmentation of the contact surfaces, in order to avoid the associated computational cost and implementation burden.”
A dual mortar approach for 3D finite deformation contact with consistent linearization (2010, methodology): “It should be noted that the authors in [25] and more recently in [12] also consider a type of 2D mortar-based contact employing a direct Lagrange multiplier approach, yet deliberately replace the mortar-typical interface segmentation and integration by an approximate integration scheme, which promot”
On the contact domain method: A comparison of penalty and Lagrange multiplier implementations (2012, background): “However applications of Lagrange multiplier based formulations are widespread till date and they can be found in [5,10,20], to name a few.”
