It is a fact that the elastic behaviors of materials (especially of metal materials) are hardly affected by strain rates because the elastic wave speeds are much higher than the plastic ones.
The specimens are made of two metal materials, 45# steel and LY-12 aluminum; the sizes are both Φ7mm×7mm.
The materials of the input bar and the output bar were described as linear elastic model with Young's modulus 200GPa, Poisson's ratio 0.3 and density 7.85×103kg/m3.
The Poisson's ratios of the two materials were both set as 0.3.

Introduction The discovery of mesoporous crystalline materials in 1992 at Mobil Oil Research and Development [1,2] raise the interest of scientists who working in zeolite area and relating materials, catalysis, and materials science [3,4].
A great number of potential application of these materials in the catalysis and separation area [5] and advanced materials [6,7] have been developed in a short period of time.
Then, the sample presents a fine distribution of pores size typical of MTS materials.

Manufacture Natural or silicone rubbers are the materials which are most often used as matrices of magnetorheological elastomers.
The designed pressing technology made it possible to produce isotropic and anisotropic materials.
This means that these materials have a high application potential.
