Nitsche’s finite element method for model coupling in elasticity
Peter Hansbo, Mats G. Larson · Computer Methods in Applied Mechanics and Engineering · 2022
We develop a hybridized Nitsche finite element method for a two dimensional elastic interface problems. Our approach allows for modelling of Euler–Bernoulli beams with axial stiffness embedded in an elastic bulk domain. The beams have their own displacement fields, and the elastic subdomains created by the beam network are triangulated independently and are coupled to the beams weakly by use of Nitsche’s method.
