“…Material properties GE, JE laminates along with JRJ sandwich composite plates are considered in the present study. The properties of GE, JE, and JRJ are derived from [27][28][29][30][31][32]. Table 1 gives the material properties of GE and JE, and Table 2 gives the properties of jute and rubber.…”

“…Damages such as matrix cracking and delamination are expected in the FRPs subjected to LVI, which are barely visible through visual inspection, and it appears that the component is undamaged [4][5][6]. Hence, to prevent the catastrophic failure of the components made by FRP composites, the study of the behavior of FRP composites subjected to LVI has received considerable attention [2,[7][8][9][10].…”

In the present study, a comparative study of the damage behavior of Glass-Epoxy (GE), Jute-Epoxy (JE) laminates with [0=90] s orientation, and Jute-Rubber-Jute (JRJ) sandwich is carried out by ABAQUS/CAE nite element software. The GE, JE laminate, and JRJ sandwich with a thickness rate of 2 mm are impacted by a hemisphericalshaped impactor at a velocity of 2.5 m/s. The mechanisms by which the brittle laminate gets damaged are analyzed in accordance with Hashin's 2D failure criterion, and exible composites are analyzed by the ductile damage mechanism. The absorbed energy and the incipient point of each laminate were compared. According to the results, there was no evidence of delamination in JRJ as opposed to GE and JE. The compliant nature of a rubber plays a role in absorbing more energy, which is slightly higher than the energy absorbed in GE. Moreover, it was observed that there was no incipient point in JRJ sandwich, meaning that there was no cracking of matrix since the rubber was elastic material. Thus, the JRJ material can be a better substitute for GE laminate in low-velocity applications. The procedure proposed for the analysis in the present study can serve as a benchmark method for modeling the impact behavior of composite structures in further investigations.

“…This was demonstrated to be an excellent method for modelling larger components subjected to complex loading conditions including impact regimes while providing good accuracy in predicting the failure behaviour when compared with experimental validation (see e.g. [2][3][4][5][6][7]). For this mesoscale modelling approach, it is very important to include all six degrees of freedom in a solid-element formulation based on the 3D continuum elasticity theory.…”

Part I of this study covered ballistic tests, in which both solid (steel) and fragmenting (ice) spherical projectiles were fired at specimens of carbon-fibre-reinforced polymer (CFRP) composite. The velocity of impacts varied from 70 to 90 m/s for the solid projectiles and from 300 to 500 m/s for the fragmenting projectiles, resulting in three consistent and comparable levels of structural damage for both types of projectiles. The observed dynamic deformation behaviour and resultant damage were examined using a combination of non-invasive analysis techniques. The focus of this Part II is on the development of a mesoscale modelling strategy for CFRP employing a phenomenological continuum-damage approach. The developed model was validated against the data from original ballistic-impact experiments, demonstrating accurate predictions of both deformation behaviour and observed resultant damage of tested specimens for the various experimental loading conditions without modification of the modelling parameters.

“…Numerous studies have been carried out to investigate the low velocity impact response of laminated composite structures. A reference list and a summary of some important earlier numerical studies is reported in a recent paper [5]. Furthermore, an extensive literature review for contact and impact dynamics is provided by Gilardi and Sharf [6].…”

A model of low-velocity impact damage assessment of laminated composite structures

Laminated composites have important applications in modern aeronautical structures due to their extraordinary mechanical and environmental behaviour. Nevertheless, aircraft composite structures are highly vulnerable to impact damage, either by low-velocity sources during maintenance or high-velocity sources during in-flight events. Even barely visible impact damage induced by low-velocity loading, substantially reduces the residual mechanical performance and the safe-service life of the composites structures. Despite the extensive research already carried out, impact damage of laminated composite structures is still not well understood and it is an area of on-going research. Numerical modelling is considered as the most efficient tool as compared to the expensive and time-consuming experimental testing. In this paper, a finite element model based on explicit dynamics formulations is adopted. Hashin criterion is applied to predict the intra-laminar damage initiation and evolution. The numerical analysis is performed using the ABAQUS® programme. The employed modelling approach is validated using numerical results found in the literature and the presented results show an acceptable correlation to the available literature data. It is demonstrated that the presented model is able to capture force-time response as well as damage evolution map for a range of impact energies.
