DOI: 10.1002/nme.7039
Abstract: We use the augmented Lagrangian formalism to derive discontinuous Galerkin (DG) formulations for problems in nonlinear elasticity. In elasticity, stress is typically a symmetric function of strain, leading to symmetric tangent stiffness matrices in Newton's… read more here.

DOI: 10.1002/qj.3756
Abstract: Accurate forecasting of air quality demands better estimates of aerosol emissions. The accuracy of conventional bottom‐up approaches to estimate aerosol emissions depends on the degree to which various influencing parameters are estimated. The availability of… read more here.
