Adaptive element-free Galerkin method applied to the limit analysis of plates (2010, methodology): “The scheme was then adapted to lower bound limit analysis by using quasivelocities and plastic multipliers from the dual solution [15].”
Upper and lower bounds in limit analysis: Adaptive meshing strategies and discontinuous loading (2009, methodology): “A similar criterion has been suggested in [18].”
Lower bound limit analysis of an anisotropic undrained strength criterion using second‐order cone programming (2018, methodology): “This technique of deducing a quasi‐velocity field has previously been used to study the mesh adaptivity in FELA.10,62 Figure 6 shows the stress contours of σ3 for smooth and rough footings using the SP strength condition (Table 1), which is superimposed with the predicted corresponding quasi‐velocit”
Application of discontinuity layout optimization to plane plasticity problems (2007, background): “Adaptive mesh refinement schemes can potentially overcome this problem (e.g. Lyamin et al. 2005), although it might be argued that the resulting analysis procedure is overly complex considering the simple rigid-plastic material idealization involved.”
