Numerical modeling of breakout process of objects lying on the seabed surface

Experimental Investigation of Skirted Foundation in Sand Subjected to Rapid Uplift

“…Theoretical solutions and procedures for estimating the pullout capacity of skirted foundations in sand are proposed by Houlsby et al (2005), Senders (2008), Lehane et al (2014) and Sawicki et al (2016). Numerical analyses have been performed by Rahman et al (2001), Zhou et al (2008), Mana et al (2014), Thieken et al (2014), and Shen et al (2017). A recent experimental study in a centrifuge is presented in (Wang et al 2019), and pullout capacities measured in 1g model tests are reported by Fig.…”

A limit analysis approach to uplift bearing capacity of shallow plate anchors in marine environments

“…Once again, if an interface with a tensile stress threshold such as described in Equation ( 12) is adopted, the upper bound pullout for this class of failure mechanism will be the same described by Equation (34), where 𝐹 𝑠𝑢𝑝 and 𝐹 𝑖𝑛𝑓 are now described by Equations ( 54) and (55), respectively.…”

“…The effectiveness of the kinematic approach in the context of effective stress analysis described in the preceding section relies on the ability to evaluate the suction forces magnitude $${F_p}$$. In that respect, the present analysis is based on the model developed by Foda, 27 which is supported by strong theoretical framework, validation, and acceptance 31–37 . Since the original work was formulated for axisymmetric and two‐dimensional anchors under plane strain conditions, the applicability of the approach will be extended herein to rectangular anchor configuration.…”

“…In that respect, the present analysis is based on the model developed by Foda, 27 which is supported by strong theoretical framework, validation, and acceptance. [31][32][33][34][35][36][37] Since the original work was formulated for axisymmetric and two-dimensional anchors under plane strain conditions, the applicability of the approach will be extended herein to rectangular anchor configuration. This section starts by providing a brief overview of the formulation originally proposed by Foda 27 and related to estimate 𝐹 𝑝 for both circular and rectangular anchors.…”
