Shear Bands with Dilatancy modelled with Underworld

Shear Bands with Dilatancy modelled with Underworld

In honour of Hans Mühlhaus' 70th birthday this month, here are some shear band simulations made with Underworld. We are investigating the role of dilatancy in the geometry of the shear bands for a box of material when a small trapdoor is opened. The extent to which large-scale deformation

Underworld 2

Underworld 2

(aka the Underworld renovation project) Underworld [https://www.underworldcode.org/] is our parallel, particle-in-cell, finite element geodynamics code [1]. For the past year or so, the Underworld team [http://www.facebook.com/underworldcode] has been working on a refurbished user interface. We've known for a long time that

The Dynamics of Continental Accretion

The Dynamics of Continental Accretion

In a recent paper [1], we used Underworld models to examine subduction congestion associated with the ingestion of a continental ribbon. The SE Australian geological record turned out to be a wonderful place to study this process. Here is a short summary of the work for a relatively non-technical audience
