In mechanics and geodynamics, a critical taper is the equilibrium angle made by the far end of a wedge-shaped agglomeration of material that is being pushed by the near end. The angle of the critical taper is a function of the material properties within the wedge, pore fluid pressure, and strength of the fault (or décollement) along the base of the wedge. In geodynamics the concept is used to explain tectonic observations in accretionary wedges. Eve… WebMar 20, 2012 · Critical cohesionless wedges are self-similar and have constant taper angle and stress orientation throughout their interior.
