Investigation of the Material Point Method in the simulation of Cone Penetration Tests in dry sand

Modelling unsaturated soils with the Material Point Method. A discussion of the state-of-the-art

“…The thickness of the soil domain is 1 m and the radius of 84 cm, loaded by 50 kPa constant in time. The computational mesh and numerical settings are equivalent to the one used by Martinelli and Galavi [55] for dry sand, but here unsaturated soil is considered. The soil behaviour is simulated using Mohr-Coulomb model with friction angle = 28 • and zero cohesion.…”

“…In particular, slope instabilities, failure of earth retaining structures, tunneling and underground collapses, soil penetration testing, pile installation, scour, internal erosion, among others [e.g. 11,12,13,14,15,16,17].…”

Long-Term Response of Piles to Cyclic Lateral Loading Following Vibratory and Impact Driving in Water-Saturated Sand

“…A numerical method able to model large-deformations is required for the analysis of pile installation processes. Simulations using the Coupled Eulerian-Lagrangian (CEL) method (Qiu et al, 2011;Henke, 2014;Hamann et al, 2015;Fan et al, 2021c;Bienen et al, 2021), the (Multi-Material) Arbitrary Lagrangian Eulerian method (Liyanapathirana, 2009;Tolooiyan and Gavin, 2011;Dijkstra et al, 2011;Aubram et al, 2015;Yang et al, 2020), the Material Point Method (Phuong et al, 2014;Hamad, 2016;Ceccato and Simonini, 2017;Giridharan et al, 2020;Martinelli and Galavi, 2021), the Particle FEM (Hauser and Schweiger, 2021;Monforte et al, 2021;Zhang et al, 2021), the Discrete Element Method (Ciantia et al, 2016;Li et al, 2019) and the Smoothed Particle Hydrodynamics method (Cyril et al, 2019) are reported in the literature. A discussion of the different methods as well as of their advantages and disadvantages in applications to geotechnical boundary value problems is out of the scope of this work.…”

A finite deformation multiplicative plasticity model with non–local hardening for bonded geomaterials

“…However, given the high deformability typically observed in bonded soils when affected by mechanical and/or chemical bond degradation, geometric non-linearity may play an important role in some practical applications. These applications include: the evaluation of pile bearing capacity of offshore platforms (McLelland, 1988;King and Lodge, 1988); the modeling of subsidence phenomena associated to hydrocarbon extraction (Potts et al, 1988) and sinkhole formation (Mánica et al, 2020); the study of the effects of pile driving (Jardine et al, 2018); the interpretation of cone penetration tests under undrained or partially drained conditions (Ceccato and Simonini, 2017;Monforte et al, 2018;Martinelli and Galavi, 2021); the modeling of slow slope deformations in presence of significant modifications of the slope geometry (Conte et al, 2019). Notable exceptions are the recent works of Monforte et al (2019) who have extended to finite deformations the Gens-Nova model (Gens and Nova, 1993), and of Oliynyk and Tamagnini (2020), who presented a finite deformation version of the theory of hyperplasticity (Houlsby and Puzrin, 2007) and applied it to the micromechanically inspired plasticity model for bonded, crushable granular materials of Tengattini et al (2014).…”
