Plastic Deformation Mechanisms in Axially Compressed Metal Tubes Used as Impact Energy Absorbers
نویسنده
چکیده
-The characteristics of a number of metal components proposed as impact energy absorbers are reviewed, attention being focussed on to modes of deformation which stem from the axial compression of metal tubes. Progressive buckling, inversion and splitting are discussed and areas for future work identified. The buckling of thin-walled square section tubes filled with polyurethane foam is also described. Reference is also made to recent work on cellular materials which highlights the influence of inertia in axially compressed tubes and tubular arrays.

The Effect of Fe Additive on Plastic Deformation for Crush-Boxes with Closed-Cell Metal Foams, Part II: Al-Composite Foam-Filled brass tubes Compression Response
The brass tubes with foam cores of AlSi7SiC3, AlSi7SiC3Fe1 and AlSi7SiC3Fe3 were produced as the crush-boxes with circle and square cross-section. Then axial compressive behavior and energy absorption capability of the foam-filled tubes were investigated during the quasi-static progressive plastic buckling. The uniaxial compressive stress–strain curves of the foam-filled brass tubes exhibited t...

متن کاملStudy on new crashworthy buffers in railway
At the collision time, a lot of energy is generated during a short period of time that causes large deformations in bodies. One of the most important parts of wagon in railway is a buffer which may absorb the energy during an impact. It should be mentioned that normal buffers only absorb the energy resulted from a crash elastically. In the present paper, it is tried to use inversion mode of ...
