Furthermore, the long-range forces are assumed to be proportional to a proper, material-dependent, distance-decaying function and to the products of the interacting volumes.
These latter are body forces modeled as proportional to the volumes of interacting elements, to a proper distance-decaying function dependent on the material and to the relative displacements between volume elements.
In Eq.(4) ( ),g x ξ is a scalar, real-valued and symmetric function, i.e. ( ) ( ),, g g=x ξ ξ x ; also, it is material dependent and distance decaying, that is it belongs to the functional class ( ) ( )11 2 2 1 1 2 2 , , g g< ∀ − > − x ξ x ξ x ξ x ξ .

The plasma frequency of the above two materials are about 6.5eV.
The peaks appears in these materials are directly related to the transition of the electrons from lower energy band to conduction band.

Steel box beam adopts materials with high strength, so its components have high strength, light height, good wholeness, nice figure.
Now various engineering’s prefer structures which have large spans and light weights, so it is very important to reasonably and fully use constructing materials in structural design [1].
