GeoGreensFunction

Commonly used Green's function in geoscience.

• Line (2 nodes) antiplane dislocation

• Line (2 nodes) inplane dislocation (check Errata)

• Rectangular (4 nodes) dislocation (limited rotational freedom)

• Triangular (3 nodes) dislocation (singularity avoided)

• Rectangular (4 nodes) dislocation (fully rotational freedom)

• Rectangular (4 nodes) antiplane strain

• Rectangular (4 nodes) inplane strain

• Triangular (3 nodes) antiplane strain

• Triangular (3 nodes) inplane strain

• Hexahedron (8 nodes) volume strain

• Tetrahedron (4 nodes) volume strain
