“…To date, a considerable amount of literature has been published on the energy absorption characteristics of composite materials affected by many factors, such as fiber and matrix property [12][13][14], fiber orientation [15; 16], hybridization [17], layup [18], geometry dimension and shape [8; 10; 16; 19; 20], trigger mechanism [21][22][23][24][25] and filler [6; 26]. Through these studies, it can be found that the crushed tubes subjected to axial crushing compression deform in various failure mechanisms, involving delamination, crack propagation, fiber breakage, matrix crack, fiber-matrix debond, lamina bundles fracture and bending etc.…”

“…23 In another study, Greve and Pickett 27 simulated a composite cantilever beam and reported similar results for the displacement of the tip in the stacked shell models, compared to the one-shell model. [29][30][31] Heimbs et al 32 used this approach to predict delamination in low-velocity impact on prestress plates problems. Several works have been published using stacked shell modelling approach in energy absorbing elements.…”

One of the most important events during an aircraft's service life is the impact of a bird (ie, bird strike), which could possibly lead to catastrophic failure. According to airworthiness authorities, compliance of an aircraft structure to bird‐strike certification specifications can potentially be proved by simulation. In the present work, combined experimental and numerical investigations are performed, aiming to provide a validated numerical simulation tool for the certification of a composite leading edge structure. To increase the numerical simulation efficiency, the stacked shell approach in the frame of the finite element method is adopted. Comparison of numerical and experimental results shows that the proposed methodology is very promising for the simulation of impact events on complex composite structures. The proposed methodology has been applied for the development of a numerical tool for the simulation of bird strike on a composite leading edge structure.

“…The improved specific energy absorption capabilities of structures made from composite materials, as compared to those made from metals, have been well-documented [ 9 , 10 , 11 , 12 ]. This improvement is because composite materials absorb energy through a variety of failure modes such as delamination, fragmentation, buckling, fibre breakage and matrix cracking while crushing progressively [ 13 , 14 , 15 ].…”

Predicting Composite Component Behavior Using Element Level Crashworthiness Tests, Finite Element Analysis and Automated Parametric Identification

Fibre reinforced plastics have tailorable and superior mechanical characteristics compared to metals and can be used to construct relevant components such as primary crash structures for automobiles. However, the absence of standardized methodologies to predict component level damage has led to their underutilization as compared to their metallic counterparts, which are used extensively to manufacture primary crash structures. This paper presents a methodology that uses crashworthiness results from in-plane impact tests, conducted on carbon-fibre reinforced epoxy flat plates, to tune the related material card in Radioss using two different parametric identification techniques: global and adaptive response search methods. The resulting virtual material model was then successfully validated by comparing the crushing behavior with results obtained from experiments that were conducted by impacting a Formula SAE (Society of Automotive Engineers) crash box. Use of automated identification techniques significantly reduces the development time of composite crash structures, whilst the predictive capability reduces the need for component level tests, thereby making the development process more efficient, automated and economical, thereby reducing the cost of development using composite materials. This in turn promotes the development of vehicles that meet safety standards with lower mass and noxious gas emissions.
