The phase field method for geometric moving interfaces and their numerical approximations (2019, unknown): “While many works on isogeometric analysis are based on the Galerkin approach, there are also works that adopted other formulations like collocation method [372] and discontinuous Galerkin method [447].”
The non-symmetric Nitsche method for the parameter-free imposition of weak boundary and coupling conditions in immersed finite elements (2016, methodology): “We note that isogeometric collocation [67] is another recent analysis technology with optimal accuracy in the derivatives, but reduced convergence rates in the L(2) error that has been successfully applied for structural analysis [6, 42, 64].”
A phase field formulation for hydrogen assisted cracking (2018, methodology): “The method has received increasing attention since the earlier work by Francfort and Marigo [11] and important efforts have been devoted to improve solution schemes [12,13], discretization strategies [14,15] and implementation aspects [16,17].”
