“…As in the proposals of Morye et al [11] and Naik et al [8,20,24], the model considers several energy-absorption mechanisms: energy absorbed by fibres (E FB ), energy absorbed in terms of acceleration field within the laminate (E KL ); energy absorbed by delamination (E DL ), and matrix cracking (E MC ).…”

“…Shear-plug formation is not observed for thin glass-reinforced composites [8]. Such mechanisms as matrix or delamination failure are less relevant than fibre failure, especially in thin glass-reinforced laminates [7,8,11], for which the energy absorbed by fibre deformation and failure, and laminate acceleration, are the main mechanisms [7,8,11]. In thick glass-reinforced laminates, delamination and matrix-crushing mechanisms could be a relevant energy-absorption mechanism.…”

a b s t r a c tThis work examines the energy-absorption process in thin woven laminates made from carbon fibres, with the aim of analysing the energy employed in the formation of a shear plug. This study was conducted with a simplified model which considered five energy-absorption mechanisms. The model was validated with experimental tests and numerical simulations, with regard to the residual velocity of the projectile and perforation velocity. The model makes it possible to evaluate the influence of the shear plugging in laminates of different thickness. It has been demonstrated that this energy-absorption mechanism needs to be considered in the analysis. The main energy-absorption mechanisms for impact at low velocity (i.e. below the perforation velocity) are related to the elastic deformation of fibres and shear plugging, whereas when a higher impact velocity is considered (i.e. above the perforation velocity) such mechanisms are related to the acceleration field of the laminate and the shear plugging.

“…For the present study an analytical model was developed, based on the models of Naik et al [15], Moyre et al [16] and Vinson and Walter [18], while adding the effect of an in-plane preloading. This model allows an estimate of the residual velocity of the projectile (hence the ballistic limit) and the energy absorbed during the penetration of the laminated plate (E AB ).…”

“…(3)) at an instant of time t i . For the calculation of E ABi , Moyre et al [16] proposed two energy-absorption mechanisms: tensile failure of the primary yarns (E TFi ), and elastic deformation of the secondary yarns (E EDi ). In addition to these, two new terms were added to improve the model accuracy: delamination damage (E DLi ) and matrix cracking (E MCi ), which were proposed by Naik et al [15].…”

In this work, the effect of a biaxial preload in the behaviour of glass/polyester woven laminate plates subjected to high velocity trans versal impact was studied. For this, an analytic model based on energy considerations that include the presence of an in plane preload was used. The results of the analytic model for the biaxial preload state were compared with those found for a non preload plate, the difference between them being minimal for the pre stressed level reached in the tests (31% of the static UTS). Therefore, numerical simulations were made in order to study the effect of the preload in greater detail; furthermore, experimental tests were conducted, validating the analytic and numerical model. In general, the two methods revealed minimal differences between the values of the ballistic limit and those of the residual velocity.

“…In a few occasions, due to the flying debris, sandwiches may come under the influence of low velocity impact load [6]. PMCs are used widely in sandwiches as they delay the shot as it diminishes its KE [7]. Projectile impact contemplates on PMCs and a sandwich board has predominantly concentrated in the low velocity impact regime in light of its relationship with BVID [8][9][10].…”

Abstract. Sandwich structure offer more advantage in bringing flexural stiffness and energy absorption capabilities in the application of automobile and aerospace components. This paper presents comparison study and analysis of two types of composite sandwich structures, one having Jute Epoxy skins with rubber core and the other having Glass Epoxy skins with rubber core subjected to low velocity normal impact loading. The behaviour of sandwich structure with various parameters such as energy absorption, peak load developed, deformation and von Mises stress and strain, are analyzed using commercially available analysis software. The results confirm that sandwich composite with jute epoxy skin absorbs approximately 20% more energy than glass epoxy skin. The contact force developed in jute epoxy skin is approximately 2.3 times less when compared to glass epoxy skin. von Mises stress developed is less in case of jute epoxy. The sandwich with jute epoxy skin deforms approximately 1.6 times more than that of same geometry of sandwich with glass epoxy skin. Thus exhibiting its elastic nature and making it potential candidate for low velocity impact application.
