Phase field modelling of crack propagation, branching and coalescence in rocks
, 2018 We present a phase field model (PFM) for simulating complex crack patterns including crack propagation, branching and coalescence in rock. The phase field model is implemented in COMSOL and is based on the strain decomposition for the elastic energy ...

Engineering Reports, Volume 7, Issue 10, October 2025.The 2D, steady, laminar forced convection of a Carreau hybrid nanofluid (MgO–Ag/water) in a modified T‐shaped cavity with two outlets and a bottom inlet is investigated numerically in current work. The cold nanofluid enters from the inlet at the bottom with Tc$$ {T}_c $$ and velocity uc$$ {u}_c $$, while the vertical L‐shaped walls (W1$$ {W}_1 $$ and ...

, 2004 The aim of this chapter is to provide an in-depth presentation and survey of meshfree particle methods. Several particle approximations are reviewed; the SPH method, corrected gradient methods and the moving least squares (MLS) approximation. The discrete equations are derived from a collocation scheme or a Galerkin method. Special attention is paid to

Natural Sciences, Volume 5, Issue 4, October 2025.The study presented investigates the thermo‐mechanical behavior of a sandwich structure with a tetrachiral‐shaped auxetic core. The geometric configuration, unit cell architecture, and the influence of the material length scale on the effective stiffness under temperature variation are illustrated.

Integration of Physics‐Based and Data‐Driven Approaches for Landslide Susceptibility Assessment
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 13, Page 3060-3097, September 2025.ABSTRACT Rainfall‐triggered landslides pose a significant threat to communities and infrastructure around the world. Various data‐driven and machine learning (ML) based algorithms have been applied to assess landslide susceptibility. However, purely data‐driven methods are affected by issues such as uncertainty in the selection of landslide ...

Single‐Asperity Friction and Wear in Seismic Faults: 2. DEM Simulations
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.Abstract Seismic faults are rough, and their geometrical complexity is an important research topic. In this work, we present a numerical model dedicated to the simulation of friction and wear in an idealized fault asperity, taking inspiration from an experimental device used in a companion paper.

International Journal of Mechanical System Dynamics, Volume 5, Issue 2, Page 345-353, June 2025.ABSTRACT In this article, the physics informed neural networks (PINNs) is employed for the numerical simulation of heat transfer involving a moving source under mixed boundary conditions. To reduce computational effort and increase accuracy, a new training method is proposed that uses a continuous time‐stepping through transfer learning.
