DESCRIPTION:Prof. Ludovic Noel\nDG is now commonly used to solve hyperboli
 c problems and\, more recently\, has been used to solve elliptic problems.
  This method\, based on the use of discontinuous test functions\, allows e
 nforcing weakly the compatibility condition through element boundary integ
 ral terms. Discontinuous Galerkin methods can also be applied to enforce w
 eakly the C1 continuity required by high-order formulations\, which leads 
 to displacement field only methods (nodes have no degree of freedom of rot
 ation). This method can be applied advantageously to non-linear shell prob
 lems where the C1 continuity must be guaranteed. In that case\, only C1 is
  enforced by recourse to the DG method while the displacement field is con
 tinuous.\n\nBut by considering discontinuous test functions and interface 
 elements in this formulation for thin structures\, a new full-DG formulati
 on is obtained.\n\nThis new formulation can be used to solve fracture prob
 lems\, as extrinsic cohesive law can easily be combined to the method\, as
  it has already been shown for solid mechanics problems.\n\nIn this work\,
  such a displacement field approach is developed for thin structures\, and
  more particularly to beams.
