Explicit dynamics “SPH – Finite Element” coupling using the Arlequin method

Abstract

The Arlequin method gives a simple and effective framework to glue models using various formulations. It is extended here in explicit dynamics and used in order to link a zone showing ruptures by fragmentation meshed with Smoothed Particles Hydrodynamics (SPH) and a larger second undamaged one meshed with finite elements (FEM). This paper gives some details on the method implemented in the EUROPLEXUS code, its validation on simple benchmarks and a confrontation between numerical simulations and results of an experimental study of concrete slab resistance to projectile impacts.

Mechanical Behavior Analysis of High Strength Concrete Beams in Architectural Design: Simplified Calculation Method of Flexural and Shear Bearing Capacity

“…High-strength concrete, known for its superior compressive strength, enhanced deformation resistance, high density, and reduced porosity, is widely used in large-scale structures such as skyscrapers, expansive bridges, and unique constructions [1][2][3]. Recent advancements have seen the integration of fiber materials into high-strength concrete, significantly improving its tensile strength, compressive strength, elasticity modulus, and durability, while maintaining excellent flowability [4][5][6].…”
