“…Soutis et al (2011) studied the response of GLARE panels to air blast loading using both, ALE and ConWep methods. In other studies ALE method was also used in variety of different applications and purposes: Chafi et al (2009), Chung Kim Yuen et al (2012, Fox et al (2011), Jayasinghe et al (2013, Langdon et al (2010), Liu et al (2012), Ma et al (2013), Pi et al (2012), Spranghers et al (2013), Tai et al (2011). In order to efficiently represent FSI on higher scaled distances, other techniques like coupling of the empirical ConWep model with ALE (Todd (2010)) or ALE mapping techniques are used (Luccioni et al (2006), Zakrisson et al (2011)).…”

The Multi Material Arbitrary Lagrange Euler (MMALE) method is widely used method for numerical investigation of structural response under blast loading. However the method is very demanding for use at the other hand. In this paper are presented the results of the detailed numerical investigation in order to simplify some decisions contributing to the accuracy and efficiency of this model. The influence of mesh properties (particularly mesh size, its biasing and distance of the boundary (DoB) conditions from the deforming structure) on blast wave loading parameters and structural response is investigated in detail and based on the results minimum mesh design criteria is proposed. The results obtained are presented as a function of the scaled distance and additionally related to the radius of the charge. Validation studies were also done successfully.

“…The simulations show that the side-on pressure difference between the two chambers is a good approximation of the average pressure on the exposed area. However, the FSI simulations also show that there is a region of higher pressure in the vicinity of the holes, and the deflection profile from the FSI simulation is different than the profile obtained from the Lagrangian simulation with uniform 15 pressure load. The Lagrangian simulations with the simplified load description are capable of reproducing the global deflection pattern, but fail to capture the increased deflection around the holes due to the FSI effect.…”

“…Li et al [14] have investigated the explosion resistance of a square plate with a hole used for venting of dust explosions in the process industry, but few details were given. Langdon et al [15] have used plates with a hole as a blast mitigation technique, but the interest was not on the behaviour of the plate, but how it altered the blast wave. Schleyer et al [16] have presented a study on square plates with a central square hole, and both a simplified analytical approach and Lagrangian FE simulations showed no significant reduction in resistance.…”

“…As the use of lightweight ductile materials in protective structures increases, knowledge of the combined effect of pressure loading and fragment impact on these materials is needed. In addition to the relevance for ongoing research on the effect of combined blast and fragment loading, transient pressure loading of plates with holes is relevant for several other applications, such as deck plating on offshore platforms and bulkheads in ships [16], aircraft design [19] and the use of perforated plates for blast wave mitigation [15].…”

The combined effect of blast and impact loading against protective structures is still not fully understood. In this paper, the motivation is to investigate the combined effect of pressure and fragment loading on steel plates. To simplify the approach, it is assumed that the fragments strike and perforate the flexible target before the pressure load arrives. These perforations are idealized as pre-formed holes of generalized shapes in thin, ductile Docol 600DL steel plates, which are then subjected to controlled pressure pulses in the laboratory. The tests were carried out in a Pulse Pressure Loading Rig, and two different pressure levels were applied for each plate design. After the tests, the deflections caused by the pressure pulses were measured. Even though the plates were much deformed in some of the tests, no sign of failure was observed. Based on a number of material tests, the parameters in the modified Johnson-Cook constitutive relation were identified. Several sets of non-linear finite element simulations of the pressure loading process were then conducted. The agreement between standard Lagrangian simulations and the experimental results was in general good, but the simulations failed to give an accurate description of the deflection around the pre-formed holes. Fully coupled FSI simulations of the experimental tests were then carried out and these simulations demonstrate significant spatial variation of the pressure load. The FSI simulations also showed that this spatial variation of the pressure load influence the deflection profile, especially in the vicinity of the holes.

“…As an example, researchers (Chung Kim Yuen et al, 2005) studied the response of quadrangular stiffened mild steel plate subjected to blast loading through experimental and numerical methods and the study was continued by another group of researchers (Langdon et al, 2010), where the authors studied the performance of mild steel perforated plates toward blast loading. An investigation on metallic sandwich panel deformation and failure behavior subjected to blast loading by changing the face-sheet, core and charge mass configuration has also been performed (Feng Zhu et al, 2008).…”

This paper presents the interrelationship equation to predict the deformations of square rolled homogeneous armor steel plate subjected to spherical shape trinitrotoluene charge by using finite element analysis software i.e. AUTODYN 3D. The investigation starts by producing computer simulation process using AUTODYN 3D so that a set of experimental tests deformations' data of rolled homogeneous armor steel plate from a published work can be used to validate the computer simulations outputs and good agreements are observed. Parametric studies are then performed on the design parameters of the explosive and the rolled homogeneous armor steel plate, where the mass of the explosive and the thickness of the rolled homogeneous amour steel plate are varied and analyzed by using the AUTODYN 3D computer simulations. Curve fitting method is then performed to produce the interrelationship equation that could be utilized by researchers as an initial prediction method in determining the deformation of rolled homogeneous armor steel plate subjected to explosive charge and the interrelation equation is valid and can be utilized for a standoff distance of 200 mm, plate's thickness of 15 mm to 30 mm and explosive mass of 1.5 kg to 10 kg.
