Introduction Recently, composite materials are used for primary structures of aircrafts and vessels.
For these reasons, metals are still important materials especially for large structures.
The selection of adhesive is difficult for joints of different materials.

The solutions known as frothers materials help to keep the bubbles in a reasonably stable state on the surface.
This is for the assembly materials. as for the promoters, fuel oil and pine oil were used at a ratio of 0.1 gm per 1 kg of the ore [23], which reduces Fe2O3 to 0.025% by two flotation stages.
Precisely the process of magnetic separation and then acid treatment is preferred in concentrating the ore because of the high cost of the flotation process due to its use of many materials’ chemicals (complexes, promoters, acids).

INTRODUCTION Nonlinear behaviors of the mechanical systems described by fractional calculus frequently appear in the literature in recent years thanks to the development of fractional calculus.[1,2,3,4,5] the damping proprieties of some viscoelastic advanced polymeric materials can be accurately modeled by fractional calculus model.[6,7,8,9,10] These studies remind us that the nonlinear influence on both constitutive relationship of materials and mechanical behavior of structures cannot be ignored.
On the other hand ,as one of the important structures the dynamics of arches continue to attract researchers to know more about dynamic behavior of arches. the geometrical and material nonlinearity of arches can not be neglected in many  aspects  such as the vibration with large displacement or large strain Especially, the introduction of the damping of some viscoelastic advanced polymeric materials to the arches requires us to understand the dynamic characteristics of arches accurately.
The material parameter describes in fact the damping characteristics of polymeric materials.
