A hybridized Nitsche finite element method was developed for two dimensional elastic interface problems, allowing for modeling of Euler-Bernoulli beams with axial stiffness and weak coupling with elastic subdomains.
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.
