In the quasi-static tests, five tubes of material aluminum alloy 2Al2T4 were tested.
Two different types of LS-DYNA material models were used in the development of finite element models:   Material model 20 “MAT_RIGID”   Material model 24 “MAT_PIECEWISE_LINEAR_PLASTICITY” The particulars of these two material models are detailed in the LS-DYNA User’s Manuals [10, 11].
Material model 24 was used to model the expansion-tube and rigid material model 20 was used to model the conical-punch.

The materials of damping device generally were made of low-yield-point steel, Pb and rubber.
Superplastic materials have been given great attention as a new seismic damper since they have more suitable characteristics as damping materials such as low-deformation stress, no work-hardening and high ductility [2,3,4,5,6,7].
According to GB/T 7314-2005(in China), metallic materials-compression testing at ambient temperature, the compression specimens were prepared with gauge lengths of 12mm and 8mm diameter.

Compression samples with different volume fraction of W (20, 40, 60, and 80%) were loaded in-situ with a neutron beam at the Los Alamos Neutron Science Center (LANSCE) using the SMARTS engineering diffractometer.
Table 2 shows what ANN estimates and the original material parameters that went to FEM.
This work has benefited from the use of the Lujan Neutron Scattering Center at LANSCE, which is funded by the Office of Basic Energy Sciences (DOE).

This method starts by mixing the barium carbonate and iron oxide in order to homogenize the raw materials and takes place in a wet medium.
The solid state synthesis is a diffusion method and starts with mixing of BaCO3 and Fe2O3 to homogenize the raw materials.
Presintering process facilitates solid state diffusion of BaO and Fe2O3 and converts the raw materials into the monoferrite phase.
The raw materials used in the study were BaCO3 (purity 99 %) and Fe2O3 (purity 99 %).

It currently covers over 370 million science-related articles from both subject and institutional repositories, digital archives, patents and journal database [3].
Many articles indexed by DBLP have been published only in printed journals or proceedings [6].
The database mainly covers material from IEEE and IET [7].
The articles are grouped in four main sections: Physical Sciences and Engineering, Life Sciences, Health Sciences, and Social Sciences and Humanities [8].

Among engineering materials, carbon steel takes the lead, constituting around 85% of the global annual steel production.
Through welding, materials undergo localized alterations in their chemical composition, microstructure, and mechanical characteristics [14, 15].
