Call for Papers "SPECIAL ISSUE: Large Deformation Analysis in Geohazards and Geotechnics"

For geohazards and geotechnics, numerous problems involve large deformation, such as installation of foundations, landslides, debris flow, collapses of excavation and tunnel and the formation sinkhole. Benefitted from the sustained development of computing power, numerical simulations have become standard methods in geomechanics and its related fields. Among those numerical methods, the finite element method (FEM) features prominently in engineering practices. For FEM, however, excessive deformation of a mesh can result in numerical inaccuracies, even to the point of making calculation impossible for large deformation problems. Many researchers adopt continuous remeshing and mapping of stresses from the old elements to the new elements method to solve very large deformation (using commercial finite element programs with purpose developed submodules), but such methods are quite tedious and time-consuming to be performed. To solve the large deformation problems, different numerical approaches have been developed and successfully applied. Moreover, significant developments have been made and this topic has attracted more attention in recent years. Unfortunately, there have been no a dedicated special issue or workshop in this specialized area. This special issue will contain the original and not previously published works in the area of the applications of numerical methods on large deformation problems in geohazards and geotechnics.

Focal points of the special issue include, but are not limited to innovative applications:

(1) Mesh-based methods, such as arbitrary Lagrangian–Eulerian (ALE) and the remeshing and interpolation technique with small strain (RITSS);

(2) Mesh-free particle methods, such as smoothed particle hydrodynamics (SPH) and mesh-free Galerkin (EFG);

(3) Mesh-based particle methods, such the material point method (MPM), particle finite element method (PFEM) and the coupled Eulerian–Lagrangian (CEL);

(4) Discontinuous numerical approaches, such as the Discrete Element Method (DEM) and other coupled analysis with DEM.
