“…For the purpose of this study, the SPH method was combined with the well-known FE method at the same model through the contact fluid-structure interaction (FSI) algorithm. The SPH method has proved to be a reliable method for modelling blast response of military vehicles, as well as other structures (Antoci et al, 2007;Barsotti et al, 2012;Toussaint and Bouamoul, 2010;Toussaint and Durocher, 2008;Trajkovski, 2015;Xu and Liu, 2008). Compared to the Arbitrary Lagrangian-Eulerian (ALE) method, it is a time-efficient method because it does not require the surrounding air to be represented in the model (Barsotti et al, 2012;Trajkovski, 2015).…”

Beside this, the SPH method overcomes the 'leakage' problems of ALE when meshes involved in FSI contact are not parallel (Olovsson and Souli, n.d.;Trajkovski et al, 2014).…”

“…Only a few studies performed by Gurumurthy (2008), Johnson and Basudhar (2015) and Trajkovski et al (2016) directly compared the plate shape influence on their blast response and explicitly pointed out that V-shaped plates have best performances. Although in a few studies shape optimization analyses of blast loaded structures (Argod et al, 2010; Gurumurthy, 2008; Johnson and Basudhar, 2015; Nayak et al, 2013; Thota et al, 2011) were performed, concise and comprehensive analyses of the individual contribution of the most important parameters on blast response of V-shaped armour plates are needed.…”

Continuous improvement in the hull floor of light armoured vehicles in terms of landmine response and crew safety is required among other things, in order to meet higher demands in the market and to obtain a product safety certificate. Previous research studies have shown that V-shaped hull floors of light armoured vehicles have a better response to blast loading in terms of saving the lives of vehicle crews or reducing the number of injuries. For this reason, parametric and design optimization analyses of V-shaped hull floors play an important role in achieving an optimal, safe and cost-effective light armoured vehicle design. However, this kind of structural optimization is complex, involving a multidisciplinary fluid-structure interaction processes, as well as large structural deformations. This article presents the results of the metamodelbased parametric analysis of blast loaded armour V-plates. The contribution of most important variable parameters such as plate angle, plate thickness, explosive mass and stand-off distance to blast loading and blast response parameters was examined using a combined smooth particle hydrodynamic-finite element numerical model. The results showed that the plate angle has the greatest impact on all response parameters of the metamodel, followed by the stand-off distance and plate thickness.
