Energy absorption phenomena in materials depend on the combination of material and geometry on a macro scale level.
The ultimate aim herein is to determine an optimised geometry setup to characterise different aluminium casting materials.
Introduction Ductility is one prerequisite for the application of cast materials in crash events.

The inelastic strain tensor can be factorized into four parts, i.e., , the classic plastic strain which satisfies J2 theory and steel plates are isotropic hardening materials, , the thermal expansion strain, , the transformation dilatational strain and , the transformation plasticity strain tensor.
The above material model is implemented into the commercial finite element package ABAQUS Standard and the elastic modulus of materials are listed in the table1.

Conventional metal material has smaller damping and less energy consumption,therefore constructional elements which are made of these material will radiate strong noise due to the vibration force.It will solve the problem if use high molecular material or the damping property of metal material,because damping materials can reduce much more noise than the general materials in the same forces.C.L.
Luo[14] invented a kind of metal plastic composite materials including 45# steel and nylon 66.Experiments showed that its amplitude and natural frequency dropped and damping ratio increased in the same order modal.In his book,M.

The two most common materials have advantages and insurmountable flaws.
And its durability is superior to ordinary wood materials.
The sonic wave can enter inside the materials along the lacunas and cause friction with the materials, which will turn the energy of sound into heat.

One of the advantages of the state space approaches to handle the laminated plates/shells is that the varying material, geometric properties along the independent spatial variable, complex load and anisotropic layered materials are allowed [3-7].
For the isotropic and orthotropic materials, the explicit form of the matrices G1, G2,,andare given in Appendix.
