| Keywords: Critical taper wedge.svg en Critical taper concept in geodynamics A wedge of material with density ρ<sub>s</sub> is pushed over a slope with angle β with a horizontal line by a force σ<sub>x</sub> x is the direction parallel to the slope The wedge makes a slope with a horizontal line with angle α Forces resisting this push are 1 the load of an eventual water column above the wedge; 2 the load of the wedge working at the base of the wedge; 3 the shear strength of the base 1 is calculated by multiplying the density of water ρ<sub>w</sub> with the height of the water column D this is multiplied by the sine of angles α and β to get the component parallel to the base angle β 2 is calculated by multiplying the density of the wedge material ρ<sub>s</sub> with the height of the wedge perpendicular to the base slope H this is multiplied by the sine of angle β to get the component parallel to the base angle β 3 is given by the Mohr-Coulomb criterion If mechanical equilibrium is assumed the resisting forces are equal to the push allowing for the calculation of the critical values of α and β when the other parameters are known Any wedge under mechanical equilibrium will have a certain equilibrium α and β depending on the other parameters When the angles different from the critical angles the wedge will reshape itself by internal deformation own Woudloper 2009-05 Structural geology diagrams | ||||
