Material properties and geometry are two important design parameters which their effects should be considered in a crashworthiness analysis. In this paper, the axial impact of metallic and hybrid energy absorbing thin-walled tubes with poly-gonal cross-section is simulated using LS-DYNA software. The combined effects of changing the geometry and material properties on the mass specific energ...

Hydroxyapatite coatings have been used on metallic substrates in a variety of applications, including modifying the surface of human implants, bone osseointegration and biological fixation. In this paper, the effects of various kinds of metallic substrate on clinical and pathological results of in vivo tests are presented. Four kinds of endodontic implants i.e, stainless steel, cobalt base all...

The analysis of non-metallic inclusions is crucial for the assessment steel properties. Scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (EDS) one most prominent methods inclusion analysis. This study utilizes output generated from SEM/EDS to predict types BSE images. Prediction models were using two different algorithms, Random Forest (RF) and convolutional neural...

The article considers the study of composition non-metallic inclusions and microstructure electric arc coating using flux-cored wire Fe – C Si Mn Cr Ni Mo system. Formation was carried out ASAW-1250 automatic welding machine by investigated wire. In order to influence level contamination deposited metal with oxide inclusions, aluminum gas purification dust introduced into (instead amorphous car...
