| Abstract: |
Smoothed Particle Hydrodynamics (SPH) has become a versatile mesh-free method for modellinglarge strain solid dynamics, yet its numerous variants have led to fragmented understanding andinconsistent stability, accuracy, and robustness. This review consolidates recent advances in SPHfor solids, with a particular focus on three-dimensional continuum descriptions, and criticallyexamines major formulations along with their numerical performance. It demonstrates how aunified, variationally consistent SPH framework, expressed in first-order conservation law form,can lead to more accurate and reliable simulations. Benchmark tests and convergence analyses arepresented to evaluate current capabilities and identify remaining challenges. The review concludeswith perspectives on future methodological developments and emerging applications where SPHoffers clear advantages for modelling large deformations. |
