Crushing characteristics of axially stacked square tubes
The crushing and energy absorption characteristics of thin-walled specimens consisting of single, welded and two axially stacked plate-divided mild steel square tubes were investigated by the performance of numerous quasi-static and dynamic axial crushing tests and FEM (finite element modeling). …

Energy absorption performance of braided basalt reinforced composite tubes under axial loads
… braided basalt composite tubes associated with axial crushing loadings. A series of thin-walled and sandwich composite tubes were fabricated using braided basalt/epoxy composite and expanded polyurethane foam. The axial crushing tests of these tubes under quasi-static and impact loads were …

Blast loading of sandwich panels with thin-walled tube cores
… The progressive folding mechanism induced by axial crushing of the tubes allows for efficient dissipation of kinetic energy. The present study investigates the use of such tubes as a sandwich core material. Several thin-walled tubes are configured in parallel, between mid-steel fase sheets. A …

LS-Dyna for Crashworthiness of Composite Structures
… materials has limited their use. The study of axial crushing behavior of metal and composite tubes has become an important aspect for the design of crashworthy structures in aircraft and automotive applications. This behavior can be studied using different crushing modes based on different …

Development of a Finite Element Model for Predicting the Impact Energy Absorbing Performance of a Composite Structure
… dynamic analysis in Abaqus which simulates the axial crushing of a thin walled composite tube between two rigid plates. The modeling techniques discussed in this paper will be used as the basis for a future thesis dedicated to designing the nose cone for the Cal Poly FSAE car.</p>

Crashworthiness capability of jute and glass fibre reinforced epoxy tubes under quasi-static loading condition for automotive application
… All the tests were undergone quasi-static axial crushing of 10 mm/min. Their peak load (Pmax), mean load (Pm), energy absorption (EA) and specific energy absorption (SEA) were discussed in detail. In the study of types of five geometrical shapes (corrugated, circular, hexagonal, octagonal …

Crashworthiness analysis of ultralight metal structures
… the two walls. This research is to study the crushing behavior of the ultralight metal core and to determine the crashworthiness and the weight saving of structures composed of the two types of reinforced components, each of which may undergo axial crushing, bending, or twisting. Numerical …

Energy Absorption of Metal-FRP Hybrid Square Tubes
… ductile collapse of the metal (which can absorb crushing energy in a controlled manner) and the high strength-to-weight ratio of the composites. The relative and absolute thicknesses of metal or FRP section has a substantial effect on energy absorption of the hybrid tubes. In particular, …
