“…However, most of the research work ceased shortly after World War -II and was not resumed until 1960s (Z. Liang, et al 2007). The intensive study on concrete targets against local impact effects of hard missiles in the nuclear industry re-initiated since five decades ago.…”

Concrete is basic construction material used for most structures. However, the vital structures have to be designed as selfprotective such as nuclear plants, power plants, weapon industries, weapons storage places, water retaining structures, highway structures, and etc. These structures should have to be offer self shield against any natural disaster tragedy incidents and intentionally produced horrible incidents such as dynamic loading, incident occurs in nuclear plants, terrorist attack, missile attack, tsunami and etc. In modern science, the impact energies are crucial way to study the local impact effects on concrete structures together with the influence of relative target thickness (H/d). This study is focused on minimum required kinetic energy for perforation of the concrete structures generated by flat nose hard missile in terms of relative target thickness (H/d), by using curve fitting empirical study with the implementation of dimensional analysis of non-dimensional numbers. For verification, the proposed developed empirical formula was well compared with other established empirical formulae such as NDRC, UMIST and Semi Empirical formulae and it is expected that the outcome of the proposed formulae can be applied in design recommendations and design procedures for determining the dynamic reaction of the concrete target to foil perforation of flat nose hard missile.

“…A review of research work exposed that peak studies about concrete structures against dynamic loading were conducted from the early 1940s (Z. Liang, et al 2007). However, most of the research work ceased shortly after World War -II and was not resumed until 1960s (Z.…”

“…Most of the studies concentrated on relatively large projectiles travelling at speeds below 500 m/s. These included experimental studies (Kojima, 1991;Ohno, Uchida et al, 1992), analytical solutions (Luk and Forrestal, 1987;Xu, Keer et al, 1997;Jones, Hughes et al, 2003;Li and Chen, 2003) and FEA studies, which managed to replicate experimental results (Hanchak, Forrestal et al, 1992;Wang, Li et al, 2007;Ranjan, Banerjee et al, 2014). As mentioned above, these works concentrated on lower speed projectiles and tended therefore to ignore effects such as the erosion of the steel material, which might instead affect the results significantly in the problem considered here.…”

“…LSDyna was used to produce the model. The software had been used previously by several authors studying reinforced concrete structures, both for projectile (Wang, Li et al, 2007) and for vehicle impact (Zain and Mohammed, 2015). As the size of the model was large, and producing a relatively rapid procedure to produce damage estimates was a requirement of the project, it was decided to use a Lagrangian formulation instead of Eulerian or SPH formations used in the past by others authors (Leppänen, 2006).…”

“…With the rapid development of testing procedures, computational tools, computational mechanics, and material constitutive models, the numerical simulation of projectile impact effects becomes more reliable and economical [1][2][3][4][5][6][7][8] . To get a first order approximation of projectile impact effects, empirical formulae can be useful.…”

This paper presents an overview on the concrete structural components subjected to impact loading. The review includes empirical formulae, analytical models, and numerical simulations. Various empirical formulae on penetration depth, perforation, and scabbing limits as well as their ranges of application have been provided. It has been observed that the information available on the validation of these models is limited. There is wider scope to study the performance of well known empirical formulae. Penetration resistance function play an important role in any analytical model. It has been observed that the major limitation is rigid projectile assumption. There is scope to develop new/improved analytical models to represent projectile characteristics. The numerical simulation of concrete structural components subjected to impact loads is a complex phenomenon. From the review, it is observed that employing appropriate material model for concrete, equation-of-state, contact algorithm and definition of yield surface plays significant role in the accurate simulation of concrete structural components. There is ample scope to develop improved methodologies in terms of development of material models and contact algorithms, which can be employed in nonlinear explicit finite element analysis of concrete structural components subjected to impact loading.
