Adaptive Mesh Simulation of Passive Earth Pressure Failure
Adaptive remeshing has been used in the finite element analysis of passive earth pressure failure. This has involved the updating of meshes at regular user-specified intervals, thereby enabling the progressive development of high shear strains to be more closely modelled. For a frictionless wall and elastic-perfectly plastic material behaviour, the computed results are in close agreement with analytical solutions. In the absence of strain-softening, the minimum element size has no influence, other than to control the shear band width. A criterion has been proposed for determining mesh-update increments automatically.
