Material parameters of the model.
While material properties such as ultimate plasticity strain and material strength effecting on structural bearing capacity have not be studied, which can not deeply analyze collapse mechanism of a structure.
Parameters are as follows: elasticity modules E1=2.06e11N/m2,tangent modulus E2=1.5e9N/m2,material density r=7450kg/m3,material failure strain 0.15,0.2,0.25 and kinematic hardening model is used, strain hardening is 1%.

This can be done by performing a transmissibility test which can be used to test a wide range of polymeric materials which possess nonlinear viscoelastic properties.
In addition, the characteristic of damping is an important property of materials due to the damping capacity which is usually used to evaluate the material ability to dissipate elastic strain energy when it is subjected to vibratory loads [12].

Introduction For many years alternative polymers and composite materials have been created to replace traditional materials used for implant manufacture [1].
The science and technology fields have introduced polymer materials fitting specified requirements - polyetheretherketone (PEEK), polyetheretherketone (PEKK), and polyphenylene sulfone (PPSU); but of particular interest is the polymer material PEEK and composites based on it.
Table 1 presents the main advantages of the properties of PEEK materials in medicine.
PEEK (Polyether-ether-ketone) and its composite materials in orthopedic implantation.
