A coupled thermal-hydro-mechanical (THM) model based on the combined finite-discrete
element method (FDEM) is presented for simulating rock cracking driven by multi-physics …

Nearly thirty years since its inception, the combined finite-discrete element method (FDEM)
has made remarkable strides in becoming a mainstream analysis tool within the field of …

This paper proposes a three-dimensional heat transfer model that considers contact heat
transfer and thermal cracking in continuous–discontinuous media. The 3D heat transfer …

This study proposes a new two-dimensional finite-discrete element method (FDEM) using
dynamically inserted cohesive elements. Unlike the conventional FDEM, which sets up …

Based on the combined finite–discrete element method (FDEM), this paper presents a
moisture diffusion–fracture coupling model to simulate soil desiccation cracking. The …

Red-layer mudstone is a typical soft rock with low strength, easy weathering and
disintegration, and significant swelling. This is an important reason for the swelling …

Moisture has a great effect on the microstructure of mudstone and the stability of muddy
strata. Due to many clay minerals in mudstone, swelling deformation and even disintegration …

Based on a combined finite-discrete element method (FDEM), this study builds a coupled
thermo-mechanical model (termed FDEM-TM) to simulate thermal cracking of rock. The …

The closure behavior of fractured rock, which is a crucial characteristic, is challenging to
simulate accurately using commonly employed numerical models. To address this issue and …

Within the framework of combined finite-discrete element method (FDEM), we propose a
novel and efficient semi-adaptive contact activation approach (semi-ACAA). The semi-ACAA …
