Interaction between soil, water and structures plays an important role in many environmental and civil engineering problems, such as landslides induced by rainfall, fluidisation and sedimentation processes in submerged slopes, internal erosion in dykes, scouring around offshore structures, settlement due to consolidation processes, installation of piles in saturated soils, and many more. Modelling these processes is challenging due to soil–water coupling, soil–structure interaction and large deformations occurring.
The theoretical part of this workshop (25 October 2017) focuses on presenting the basic MPM formulation capable of simulating the interaction between solid and liquid phases and structures. The approaches of drained, undrained and fully coupled material behaviour will be addressed. The soil is modelled as a saturated porous continuum understood as a mixture of solid skeleton and pore water. The contact behaviour will be explained by showing the underlying algorithm and illustrative examples. For the soil constitutive behaviour basic soil models are available and an interface to include user-defined models is presented.
**Please note that we also offer a training course on 26 October 2017, after this Anura3D workshop**
For practical user experience a training course is organised, where participants will gain experience as users of the Anura3D MPM Software. In several training exercises, the attendees will learn capabilities of Anura3D v2017.2 by means of a set of practical problems that will be solved following a tutorial. Please register separately for the training course on the second day!
