There are two types of energy absorption capability, which are specific energy absorption (SEA) and volumetric energy absorption. SEA is described as cross-section areas in which the material is in contact with the top platen at any deformation, or in other words, SEA can be defined as the total of absorbed energy per unit mass.

Eshkoor et al. investigated the SEA of both triggered and nontriggered of plain-woven silk-reinforced epoxy composite tubes. The energy absorption capability and failure mechanism of the oil palm fiber and coir fiber-reinforced polyester composite solid cones with different vertex angles varied from 0 to 60 degrees were discussed by Mahdi et trc-music.com by: 2.

Hybrid tube beams strengthened by composite layer on the whole web and flange showed an excellent bending strength and energy absorption capability. 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.

Various inclined angles of 5°, 10°, 20° and 30° were selected for the study of off-axis loading.

The weak stiffness and strength of materials with negative Poisson’s ratio limits their application. In this paper, three types of novel lattices with negative Poisson’s ratio are proposed to improve not only stiffness and strength but also energy absorption capacity by embedding different ribs into a classic re-entrant structure.

Unit cell analyses show these novel lattices have Cited by: 3.

Dec 04,  · Similar behaviors can be observed for the volume density of energy absorption, E uv-hollow and E um-water-filled [Fig.

4(b)]. For water-filled CNTs and for the current range of parameters explored in this study, the energy absorption densities have power-law dependencies on L / R and R / t 0, which can be fitted as. Most probably the best and most remarkable mechanical property of metal foams is their energy absorption capability [60,61].

Foams can absorb a maximum of mechanical energy without exceeding a certain stress limit σ D due to plastic, irreversible deformation over a large strain range.

This property, usually isotropic, makes foams almost ideal Cited by: The value of composite columns. Structural hollow sections are the most efficient of all structural steel sections in resisting compression. They have a high strength to weight ratio and produce slender attractive lines that make them a natural choice for building structures.
