This study aimed to investigate the energy absorption characteristics of glass fiber cloth‐reinforced epoxy resin (GFRP) composites. The axial dynamic impact test and numerical simulation study on 759/5224 circular tubes were conducted, as well as analyzed and discussed the relevant energy‐absorption parameters and failure morphology. Based on continuum‐damage mechanics, considering the anisotropic constitutive model of composites, the failure criterion including stiffness degradation was embedded into the second subroutine of MSC.Dytran platform and then introduced damage variables to update the material parameters. A progressive damage‐analysis model of composites with shear nonlinear effect was also established. Based on the improved secondary subroutine damage evolution model, the dynamic impact damage morphology of 759/5224 glass–fiber composite tube was accurately simulated; used the finite element simulation to obtain the absorption evaluation parameters of average load, special energy absorption and crushing stroke; and comparatively analyzed the simulation and test results. The maximum relative error of special energy absorption of the glass–fiber composite tube was <8.5%, which met engineering requirements. Therefore, the finite‐element method adopted in this paper can reasonably evaluate the gradual failure of dynamic impact of glass–fiber composite tubes. POLYM.

The crush behavior of truncated, conical, foam-filled, empty shells subjected to quasi-static axial crushing is investigated experimentally. Epoxy resin/E-glass shells with cone angles of 0 , 11 , and 22 and with three different diameter-wall thickness ratios were tested. Polyurethane foam with a density of 55 kg/m 3 was used in filled specimens. For empty shells showing an unstable failure mode, energy absorption was increased with the cone angle. In contrast, foam-filled shells showed a stable progressive crushing failure and a reverse trend in energy absorption with the cone angle.

“…Furthermore an increase in cone vertex angle results into decrease of SEA, peak load (P L ) and volume reduction ( ) R V . Alkateb et al [79] states that crushing behaviour was under influence of vertex angle within elliptical cone design. In more details, in elliptical cone vertex angle of 12˚, an increase in vertex angle decreases crushing load.…”

The present paper reviews crushing process of fibre-reinforced polymer (FRPs) composites tubular structures. Working with anisotropic material requires consideration of specific parameter definition in order to tailor a well-engineered composite structure. These parameters include geometry design, strain rate sensitivity, material properties, laminate design, interlaminar fracture toughness and off-axis loading conditions which are reviewed in this paper to create a comprehensive data base for researchers, engineers and scientists in the field. Each of these parameters influences the structural integrity and progressive crushing behaviour. In this extensive review each of these parameters is introduced, explained and evaluated. Construction of a well-engineered composite structure and triggering mechanism to strain rate sensitivity and testing conditions followed by failure mechanisms are extensively reviewed. Furthermore, this paper has mainly focused on experimental analysis that has been carried out on different types of FRP composites in the past two decades.
