|Issue Date:||Jun-2013||Citation:||Liu, G.R., Zhou, C.E., Wang, G.Y. (2013-06). An implementation of the smoothed particle hydrodynamics for hypervelocity impacts and penetration to layered composites. International Journal of Computational Methods 10 (3) : -. ScholarBank@NUS Repository. https://doi.org/10.1142/S0219876213500564||Abstract:||Driven by applications in the design of protective structure systems, the need to model high velocity impact is becoming of great importance. This paper presents a Smoothed Particle Hydrodynamics (SPH) procedure for 3D simulation of high velocity impacts where high rate hydrodynamics and material strength are of great concern. The formulations and implementations of the Johnson-Cook strength and damage model considering temperature effect, and Mie-Gruneison and Tilloton equations of state are discussed. The performance of the procedure is demonstrated through two example analyses, one modeling a cubic tungsten projectile penetrating a multi-layered target panel and the other involving a sphere perforating a thin plate. The results obtained, with comparisons made to both experimental results and other numerical solutions previously reported, show that our SPH-3D implementation is accurate and reliable for modeling the overall behavior of the high rate hydrodynamics with material strength. © 2013 World Scientific Publishing Company.||Source Title:||International Journal of Computational Methods||URI:||http://scholarbank.nus.edu.sg/handle/10635/59468||ISSN:||02198762||DOI:||10.1142/S0219876213500564|
