WebThe critical wedge theory utilizes the angle of the basal slope (β), the internal friction angle (φ), and the coefficient of basal friction (µ b ) to determine the critical angle (α+β) that the structure will adhere to. It is represented by the equation: α + β = ((1-sin φ)/(1 + sin φ))(β + µ b WebSep 13, 2024 · The critical taper paradigm, as stated by Dahlen in the article, is “for understanding the large scale mechanics of fold-and-thrust belts and accretionary wedges.” Therefore, it does not provide a clear description of the wedge inner smaller-scale changes.

WebMay 5, 2024 · The critical taper theory is based on the assumption that the internal state of stress of a wedge composed of material deforming following the Mohr-Coulomb criterion is on the verge of failure everywhere [Davis et al., 1983]. The shape of the wedge, growing self-similarly, depends on the strength of the material and on the ... WebThe model has features predicted by the critical-taper theory: (1) overall wedge geometry; (2) crudely self-similar growth during evolution; (3) more intense deformation toward the rear of the wedge. The models show strong overall in-sequence faulting behavior with major thrusts isolating relatively undeformed packages, which are moved in a ...
