Geotechnical particle finite element method for modeling of soil-structure interaction under large deformation conditions

Autor: Josep Maria Carbonell, Lluís Monforte, Matteo O. Ciantia, Marcos Arroyo, Antonio Gens

Publikováno v: Journal of Rock Mechanics and Geotechnical Engineering, Vol 14, Iss 3, Pp 967-983 (2022)

The possibilities of the particle finite element method (PFEM) for modeling geotechnical problems are increasingly evident. PFEM is a numerical approach to solve large displacement and large strain continuum problems that are beyond the capabilities

A contact model for rough crushable sand

Autor: Ningning Zhang, Matteo O. Ciantia, Marcos Arroyo, Antonio Gens

Publikováno v: Soils and Foundations, Vol 61, Iss 3, Pp 798-814 (2021)

Sand roughness is now accessible to measurement. Incorporating this parameter into sand models using the discrete element method (DEM) is known to improve bulk small strain response. In this work we explore the effect on problems where particle crush

Homogenización de barreras de arcilla para residuos nucleares

Autor: Antonio Gens, Ramon B. de Vasconcelos, Carlos E. Rodríguez, Jean Vaunat, María Victoria Villar

Publikováno v: Geotecnia, Iss 152 (2021)

Las funciones de seguridad de las barreras de bentonita para residuos nucleares dependen principalmente del valor de su densidad seca (o porosidad). La evolución de esta variable durante la fase transitoria de la barrera es compleja. El artículo pr

Effect of thermo-coupled processes on the behaviour of a clay barrier submitted to heating and hydration

Autor: Marcelo Sánchez, Antonio Gens, Sebastia Olivella

Publikováno v: Anais da Academia Brasileira de Ciências, Vol 82, Iss 1, Pp 153-168 (2010)

The storage of high level radioactive waste is still an unresolved problem of the nuclear industry, being geological disposal the most favoured option and, naturally, the one requiring the strongest geo-mechanical input. Most conceptual designs for t

A relation between cone metrics and the state parameter for liquefiable soils

Autor: Lluís Monforte, Marcos Arroyo, Antonio Gens

Publikováno v: Canadian Geotechnical Journal.

This paper presents a new interpretation procedure to estimate the initial state parameter from cone penetration testing (CPTu) in undrained conditions based on the results from a comprehensive set of numerical simulations of CPTu in low permeability

Large-strain analysis of undrained smooth tube sampling

Autor: Josep Maria Carbonell, Antonio Gens, Lluís Monforte, Marcos Arroyo

Publikováno v: UPCommons. Portal del coneixement obert de la UPC
Universitat Politècnica de Catalunya (UPC)

Borehole tube sampling is a key process of geotechnical engineering. The paper presents numerical analyses of smooth tube sampling in clay using the Particle Finite Element Method (PFEM). The soil is described by a conventional elasto-plastic constit
