TRIANGULAR DISLOCATIONS

Triangular Dislocations: Analytical, artefact-free solution

This package consists of MATLAB functions for calculating displacements, strains and stresses associated with triangular dislocations (TDs) in a homogeneous elastic full-space or half-space. The functions implement the Nikkhoo and Walter (2015) analytical solutions that are free of artefact singularities and numerical instabilities. These solutions are also independent of the model scale and can thus be applied to a wide range of problems in geophysics, engineering and physics, without requiring any alterations in the input data or the geometry of meshes of the TDs.

COMPOUND DISLOCATION MODELS

The CDM: Compound Dislocation Model

This package contains MATLAB functions for calculating displacements, strains and stresses associated with rectangular dislocations (RDs), compound dislocation models (CDMs) and generalized point sources of pressure in a homogeneous elastic full-space or half-space. The functions implement the Nikkhoo et al. (2017) analytical solutions and the Eshelby (1957) shape tensor.

GRAVITY CHANGES DUE TO POINT TRIAXIAL SOURCES

The point CDM gravity changes

This package contains MATLAB functions for calculating gravity changes associated with triaxial volumetric sources of expansion, namely, the point Compound Dislocation Model (point CDM) and point Ellipsoidal Cavity Model (point ECM) in a uniform elastic half-space. The functions implement the Nikkhoo and Rivalta (2022) analytical solutions, which build on the Okubo (1991) and Eshelby (1957) analytical solutions.
