Interface to study soil-structure interaction in Plaxis 3D (Clay Hypoplasticity)

Leon Cortes|21.8.2018|Finite Elements|6 |

Hello, I am trying to simulate the behavior of helical anchors (also called screw anchors) using PLAXIS 3D and a clay hypoplasticity constitutive model. The helical anchor shaft is simulated […]

Multilaminate Model (Schädlich & Schweiger)

Helmut Schweiger|1.3.2018|Constitutive Models|0 |

Multilaminate constitutive models are based on the concept that the material behaviour can be formulated on a number of so-called integration planes with varying orientation. In addition to other features, the model predicts anisotropic soil stiffness at small strains.
