“…The style of folding observed in the mechanical models is in general agreement with the kinematics and deformation mechanisms implied by the kinkstyle fault-propagation folding models. These findings are consistent with recent finite-element-based mechanical models in which adaptive remeshing and an evolving strain-weakening constitutive model were employed (Albertz and Lingrey, 2012;Albertz and Sanz, 2012). Likewise, they are consistent with the observation from a range of previous DEM models that mechanical layer strength contrasts have a firstorder control on fault-related folding style for thick-skinned fault-propagation folds (Cardozo et al, 2005;Finch, 2006, 2007).…”

“…Structural style in shortening environments depends on numerous factors such as sediment strength, stress state, the existence of weak planes, sediment deposition, and the pore pressure regime (Albertz & Lingrey, ; Albertz & Sanz, ; Thornton & Crook, ). For example, Hubbert and Rubey () provide a mechanical explanation for the role of overpressure in overthrust faulting in which high overpressures decrease the effective stresses in detachments and, consequently, also decreases the frictional resistance, facilitating the slide of large masses of sediment.…”

“…The SR4 yield surface is composed of two different surfaces that intersect in a continuous manner at the peak stress. The cap side, where compaction is expected to take place, is defined by the Modified Cam Clay surface, whereas the shear side is defined by means of the Soft Rock 3 (SR3) constitutive model's surface (Albertz & Lingrey, ; Albertz & Sanz, ): ϕ(p,ϵvp)=g(θ,p)q+(ppt)tanβ2.03em(ppc)(ptpc)2.03em1/n for ppϕpeak and ϕ(p,ϵvp)=1.19emg(θ,p)1.19em2q2Mϕ2pϕpeak22.03em1(pϕpeakp)2(pϕpeakpc)22.03em for p<pϕpeak…”

“…Geomechanical modelling can be employed in conjunction with advanced constitutive models to simulate sediment rheology which are capable of accounting for the full 3D stress tensor and its impact on compaction (Albertz and Lingrey, 2012;Albertz and Sanz, 2012;Luo et al, 2012;Smart et al, 2012) and overpressure generation Thornton and Crook, 2014).…”
