“…As the cost of implementing composite materials must also be considered, various studies have also been performed on hybrid metal‐composite tube configurations that combine the high mechanical properties of composites with the low cost of metals, in many cases involving aluminum . However, the studies that have been performed on hybrid metal‐composite structures for crashworthiness applications largely focus on those made with tubular components, and the amount of work done on other structural forms is rather limited.…”

This paper presents experimental and numerical investigation on the parameters effecting energy absorption capability of composite tubular structures at oblique loading to improve crashworthiness performance. Various inclined angles of 5˚, 10˚, 20˚ and 30˚ were selected for the study of off-axis loading. The results indicate that by increasing the lateral inclination angle the mean crushing force and also energy absorption capability of all tested sections decreased. From design perspective, it is necessary to investigate the parameters effecting this phenomenon. The off-axis loading effect that causes significant reduction in energy absorption was investigated and the effected parameters were improved to increase energy absorption capability. To establish this study, 10˚ off-axis loading was chosen to illustrate the obtained improvement in energy absorption capability. Five cases were studied with combinations of ply-orientation and flat trimming with 45˚ chamfer. This method was applied to the integrated 10˚ off-axis loading and the final results showed significant improvement in energy absorption capability of composite absorbers. Finite element model (FEM) was developed to simulate the crushing process of axial and off-axis composite section in LS-DYNA and the results were in good agreement with the experimental data.

“…Various methods of fabrication such as filament winding, hand lay-up and vacuum infusion were introduced to study the effect of fabrication methods on the energy absorption capabilities [9]. Different impact tests were conducted [9][10][11] to assess the role of material properties and production method on failure and fracture modes. Conical thin-walled composite structure is one of the most studied geometries in crashworthiness analysis.…”

The geometry of a composite frusta-conical structure with 20° apex angle was optimized using topology optimization method. The ATOM topology solver was used to perform optimization process. The structure was subjected to an axial compressive quasi-static loading where the criterion of optimization is the largest absorption of energy per unit volume. The optimization resulted in concave shell geometry with a volume reduction of 15%. To compare the effect of geometry on energy absorption capability, two types of GFRP specimen with different thickness were fabricated using filament winding and hand lay-up methods. The axial crushing test results were validated with numerical analysis using the commercial finite element software ABAQUS. The collapse mode and failure mechanism were investigated and identified. The presented methodology helps to find the better geometry instead of testing different geometries.
