Saturation ratio influence on perforation and penetration of concrete subjected to missile impact: a DEM approach
Concrete structures are widely used as shielding barriers to protect sensitive infrastructures. Possible accidental conditions such as aircraft impacts on nuclear containment have led to an increasing demand for advanced design of concrete structures under extreme loading. Several studies have shown that the presence of free water in concrete significantly affects its response when subjected to static loading with high mean stresses or dynamic loading with high strain rates. Therefore, the aim of this paper is to investigate the influence of the saturation ratio on perforation and penetration of concrete. To achieve this purpose, the study will simulate the impact of ogive-nosed steel projectile on three plain concrete targets, passively confined by means of steel jackets surrounding the cylindrical specimens.
期刊介绍：
GENERAL OBJECTIVES: Computational Particle Mechanics (CPM) is a quarterly journal with the goal of publishing full-length original articles addressing the modeling and simulation of systems involving particles and particle methods. The goal is to enhance communication among researchers in the applied sciences who use "particles'''' in one form or another in their research.
SPECIFIC OBJECTIVES: Particle-based materials and numerical methods have become wide-spread in the natural and applied sciences, engineering, biology. The term "particle methods/mechanics'''' has now come to imply several different things to researchers in the 21st century, including:
(a) Particles as a physical unit in granular media, particulate flows, plasmas, swarms, etc.,
(b) Particles representing material phases in continua at the meso-, micro-and nano-scale and
(c) Particles as a discretization unit in continua and discontinua in numerical methods such as
Discrete Element Methods (DEM), Particle Finite Element Methods (PFEM), Molecular Dynamics (MD), and Smoothed Particle Hydrodynamics (SPH), to name a few.
