Metal Rubber is a kind of material with nonlinear of resuming force.
This material has the elastic properties similar to rubber, and because its raw materials is metal, so it can work in high temperature, low temperature, vacuum and corrosive media.

Initially 109 different material properties were used to define the whole helicopter model including layers of composite material for the cabin floor.
Updating parameters may be material properties of substructures or groups of elements.
Then the material properties cards of these sections were given separate material property cards (PSHELL's) so that their natural frequency sensitivities to thickness changes could be studied using Solution 200 in MSC-NASTRAN.

We assume that there is 10% depth error in high and low index materials, and there are four plus one situations to be considered.
Introduction Bragg reflectors, which consist of periodically alternating quarter-wave layers with different refractive index materials, play an important role in a number of optoelectronic devices [1,2].
Here, we assume that there are 10% depth error in high and low index materials, and then there are four plus one situations to be considered.
