Study Results from A. Uhnakova and Colleagues in the Area of Computational Materials Science Reported

February 4, 2014



By a News Reporter-Staff News Editor at Journal of Technology -- Investigators discuss new findings in Computational Materials Science. According to news reporting out of Prague, Czech Republic, by VerticalNews editors, research stated, "We present new results of molecular dynamics (MD) in 3D bcc Fe-Cu crystal with embedded central through crack (001)[110] of Griffith type loaded in mode I. Such sample geometry and border conditions in MD were chosen to invoke a cleavage crack extension through a bcc Cu nano-particle placed in front of the crack."

Our news journalists obtained a quote from the research, "The stress field and bond breakage caused by the crack and Cu inhomogeneity are analysed on the atomistic level. The character of crack extension and corresponding wave patterns are studied in the Fe-Cu system."

According to the news editors, the research concluded: "The study is motivated by a question how a small Cu bcc precipitate changes the brittle behavior of the crack in comparison with pure bcc iron loaded in mode I."
