Impact Damage Resistance of Shape Memory Alloy Hybrid Composite Structures
… alloy (SMA). It was found analytically that the super-elastic SMA demonstrates a high strain energy absorption capability. The closed- form solution of the strain energy absorption capability of SMA bars is a simple and useful tool in the design of energy absorption applications of super-elastic …

Rheological and Mechanical behaviour of Block copolymers, Multigraft copolymers and Block copolymer Nanocomposites
… (EB) radiation for developing materials with superior properties. The electron beam radiation has the ability to alter material parameters at molecular level for enhancing the macroscopic properties. The desirable physical and chemical properties can be easily attained by varying the radiation …

Mass-spectroscopy and modeling of capacitive coupled hydrogen plasmas
… unusual result is explained in the hypothesis of super elastic collision of vibrationally excited hydrogenmolecule with an electron resulting in energy transfer to the electron. The mechanics such super-elastic collisions are not included in the PIC simulation, and this is consistent with the …

Electron collisions and internal excitation in stored molecular ion beams
… Dissociative recombination (DR) and inelastic and super-elastic collisions are studied in the system of He2+. The DR rate coefficient at low energies depends strongly on the initial vibrational excitation in this system. Therefore changes in the DR rate coefficient are a very sensitive …

Mechanics of periodic elastomeric structures with varying void volume fraction and thin-film coating
Super-elastic periodic structures possess special mechanical, photonic, phononic, and topological properties, making them particularly relevant for application at the micro and nano length scales. This study examines the behavior of such materials in two and three dimensions when void volume …

Inelastic collisions and recombination between electrons and molecular ions
Inelastic collisions between molecular ions and slow electrons play an important role in naturally occurring ionized media and involve interesting interaction mechanisms which are also under intense theoretical study. Several experiments focused on the collision of small molecular ions with …

Kinetic processes in a high pressure laser generated plasma
… while the ion/electron density is controlled by super elastic heating of "seed electrons" in collision with 3p atoms followed by electron impact ionization of excited atoms. Excitation transfer rates into the 4d, 5d, 6d, and 6s levels are measured. At late times (~1 μs), excited state populations …

Application of SMA fiber composite as seismic reinforcement for concrete moment resisting frames
… steel bars. However, due to their linear elastic behavior, they are not considered in structures which require ductility and damping characteristics. The use of shape memory alloys (SMAs) with their nonlinear-elastic behavior in the composite could potentially provide solution for this …

The Effect of Plastic Deformation on a Series of Thin Magnetic Films
… magnetic films of FeSi and NiFe were grown on super-elastic Nitinol using dual ion beam and magnetron sputtering techniques, then submitted to varying degrees of lateral strain to induce plastic deformation in the thin magnetic film by (1) bending over a cylinder of fixed radius and (2) …
