Upper bound sequential linear programming mesh adaptation scheme for collapse analysis of masonry vaults
Upper bound limit analysis of masonry vaults and double curvature structures. Utilization of curved, six noded infinitely resistant triangular elements. Plastic dissipation allowed on curved interfaces only. Mesh adaptation (nodes coordinate movements) with sequential linear programming. Substitution of the heterogeneous material with a homogenized continuum.
