Abstract
This paper presents the explicit stiffness matrix of the 15-noded cubic strain triangle, for a cross-anisotropic medium, which was evolved through the use of area coordinates. This stiffness matrix would be very useful in finite-element analysis of geomechanics problems such as collapse, vibration and consolidation because it will drastically reduce computer run-time through a faster assembly of the global stiffness matrix.
