Experimental and numerical (EFG method) studies on sedimentary rock under varied salinity conditions

A hydromechanical EFG-based Model for Numerical Simulation of Land Subsidence Induced by Groundwater Extraction in Anisotropic Aquifers

“…Compared to element-based models, meshless methods provide some advantages, including employing higher-order continuity for interpolation, hence attaining precise representation of stress fields, facilitating the modeling of substantial deformations without the possibility of element distortion, and enabling crack propagation simulation (Tey et al, 2020). The element-free Galerkin (EFG) technique (Belytschko et al, 1994) has been employed as a numerical modeling tool for geotechnical problems (Dinesh et al, 2021;Iranmanesh et al, 2018;Iranmanesh & Pak, 2023;Tey et al, 2020;Tourei et al, 2024) and provides a robust framework for addressing complex, nonlinear soil behaviors, offering enhanced accuracy and flexibility compared to traditional finite element methods, especially in simulations involving large deformations and irregular geometries. Pathania et al (Pathania & Rastogi, 2017 introduced a novel hydraulic model that uses the meshless EFG technique and the Moving Least Squares (MLS) methodology for simulating groundwater flow in unconfined aquifers, highlighting the advantages of meshless techniques over traditional mesh-dependent methods.…”
