“…However the nature of these phenomena is expected to be more complicated, and the response depends on interaction between the different mechanisms that control the crushing process such as transverse shearing, lamina bending, and local buckling. These failure modes further depend on the mechanical properties of the constituent materials, the structure of the specimen, the crushing speed and the crushing length [29].…”

“…This crushing mode consists of the formation of local buckles. Brittle fibre-reinforced composite materials usually do not exhibit post-crushing integrity due to the lack of plastic stress-strain response and they fail in a catastrophic mode with interlaminar cracks being formed at the buckles [29]. The mechanisms that take place during such loads can be very complex to model and further interpret.…”

The increasing demands in subsea industry such as oil and gas, led to a rapidly growing need for the use of advanced, high performance, lightweight materials such as composite materials. E-glass fibre laminated pre-preg, filament wound and braided tubes were tested to destruction under hydrostatic external pressure in order to study their buckling and crushing behaviour. Different fibre architectures and wind angles were tested at a range of wall thicknesses highlighting the advantage that hoop reinforcement offers. The experimental results were compared with theoretical predictions obtained from classic laminate theory and finite element analysis (ABAQUS) based on the principal that the predominant failure mode was buckling. SEM analysis was further performed to investigate the resulting failure mechanisms, indicating that the failure mechanisms can be more complex with a variety of observed modes taking place such as fibre fracture, delamination and fibre-matrix interface failure.

“…Accordingly, high peak crush failure load leads to catastrophic failure mechanism at initial failure crush stage, which results in low crush force efficiency (CFE) at post-crush stage as well as unstable load-displacement behaviour [18]. However, as it has been mentioned in some researches significant energy can also be absorbed when structural elements catastrophically fail [19].…”

a b s t r a c tThis paper focuses on natural silk/epoxy composite square tubes energy absorption and failure response. The tested specimens were featured by a material combination of different lengths and same numbers of natural silk/epoxy composite layers in form of reinforced woven fabric in thermosetting epoxy resin. Tubes were compressed in INSTRON 5567 with a loading capacity of 30 kN. This research investigates the influence of the wall lengths on the compressive response and also failure mode of the tested tubes are analysed. The load-displacement behaviour of square tubes recorded during the test. Since natural woven silk has been used as textile in centuries but due to rare study of this fabric as reinforcement material for composites, the results of this paper can be considerable. Outcomes from this paper might be helpful to guide the design of crashworthy structures.

“…The fragmentation of fibrereinforced composites happens under a nearly ideal constant crush load level, while the folding pattern of metallic crash boxes under compression typically leads to severe load amplitudes for each fold [14]. The characteristics of composite crash absorbers and the influence of various geometrical shapes, fibre architectures or trigger mechanisms have been investigated extensively in the past [15][16][17][18][19].…”

A composite crash absorber element for potential use in z-struts of commercial aircraft fuselage structures was developed, which absorbs energy under crash loads by cutting the composite strut into stripes and crushing the material under bending. The design concept of this absorber element is described and the performance is evaluated experimentally in static, crash and fatigue test series on component and structural level under normal and oblique impact conditions. The physics of the energy absorption by high rate material fragmentation and delamination interactions are explained and numerical modelling methods in explicit finite element codes for the simulation of the crash absorber are assessed.
