An isogeometric method for the Reissner-Mindlin plate bending problem. (English summary) Comput. Methods Appl. Mech. Engrg. 209/212 (2012), 45–53. The paper presents an application of isogeometric analysis (IGA) to the Reissner-Mindlin plate bending problem. The authors show how by using IGA it is possible to construct smooth discrete spaces that satisfy the Kirchoff constraint at the limit, obtaining an optimal locking-free formulation. Moreover, the method is able to incorporate exact CAD geometries, which is a great practical advantage. The paper contains an extensive theoretical analysis of the proposed formulation as well as several numerical tests demonstrating its effectiveness. It represents an important contribution to the numerical simulation of this type of problem. Reviewed by Luca Formaggi
