Evaluation of Shape Effects for Rectangular Anchors in Dense Sand: Model Tests and 3D Finite-Element Analysis
Publication: International Journal of Geomechanics
Volume 12, Issue 2
Abstract
In this study, three-dimensional finite element models, incorporating an elastoplastic material model coupled with isotropic simple softening law, nonassociated flow rule, and shear-band effect, are validated for the evaluation of the shape effect of the square and rectangular vertically uploaded anchor foundations embedded in dense Toyoura sand with embedment ratio of 2 and width of . The proposed numerical model has closely predicted experimental uplift load-displacement relationships. The shape effects on the results are also discussed in relation to the progressive failure around the foundations and the shape of the failure boundaries on the ground surface.
