Stability of accretionary wedges based on the maximum strength theorem for fluid-saturated porous media

► Provide an extension of the kinematics approach of limit analysis to porous media. ► Validation of the theory by comparing the results with the classical critical-taper theory. ► Application to the Barbados to find the in-situ pressure ratios. ► Application to heterogeneous décollement to prove the existence of a new failure mode.
