Improve Shell Model Accuracy for Torsion in Abaqus
Drill DOF tuning improves torsional stiffness in composite shell models. When simulating wind turbine blades under torsional loads, shell models are often preferred over solid models for efficiency. But standard shell formulations can significantly underestimate torsional stiffness, especially when offsets and layered orthotropic materials are involved. A joint study by Ghent University and 4RealSim, published in Composite Structures, Volume 280 (2022) , demonstrates that tu

Discrete Element Modeling in Abaqus
DEM simulation of a spud can penetrating a seabed with dynamic rock fill Simulating Granular Particle Behavior With Abaqus/Explicit Granular materials, such as rock fill, shot peening media, or pharmaceutical granules, don’t behave like typical solids. Their bulk response isn’t governed by internal deformation, but by frictional contact and motion between rigid particles. For these cases, the Discrete Element Method (DEM) in Abaqus/Explicit offers a purpose-built approach to
