The macro-mechanical behavior of crystalline rocks including strength, deformability and
failure pattern are dominantly influenced by their grain-scale structures. Numerical …

In this work, three extensions to the traditional discontinuous deformation analysis (DDA)
method are tested to simulate the entire process describing the behavior of landslides …

To analyze the movement of discrete rock block systems, a nodal-based three-dimensional
discontinuous deformation analysis method with contact potential (3D-NDDACP) is …

A satisfactory balance between solution precision and computational efficiency can be
achieved via mixed-order elements, however, the generality and robustness of commonly …

Debris flow frequently occurs in mountainous regions and can cause serious damages to
residents and structures in susceptible areas. Conventional debris flow simulation (DFS) …

This work modified the generalized maximum tangential stress (MTS) criterion by taking
parallel and perpendicular nonsingular stresses, ie, T x and T y, into account. When applied …

The discontinuous deformation analysis (DDA) is a numerical method for modeling
discontinuous deformation behaviour of jointed rocks. In this paper, two basic problems are …

Abstract In the classical Discontinuous Deformation Analysis (DDA) the contact conditions
are enforced by what is referred to as open–close iteration. The open–close iteration …

In the present work, a nodal-based continuous-discontinuous deformation analysis
(NCDDA) method is proposed to simulate the failure process of rock masses. A strategy of …

Joint property in three-dimensional discontinuous deformation analysis (3-D DDA) is crucial.
The joint property in a contact relies upon just one of the contacting objects in original 3-D …
