+    <description descriptionType="Other">MATLAB scripts that implement the analytical solution for the fricitonal anisotropy of a serrated surface, with teeth inclination angle 'alpha' and friction angle 'phi'. The script PlotSolution.m permits plotting the analytical solution in Cartesian and polar plots. The script Reactivation.m applies the solution to asses fault reactivation due to a uniform increase in pore fluid pressure. Local functions are defined at the end of the scripts. A function that returns the analytical solution (frictionalaniso.m) is used by both scripts.
