A COMBINED FIRST PRINCIPLES AND MOHR-COULOMB CRITERION FOR THE DETERMINATION OF THE NANOHARDNESS OF AMORPHOUS SILICON

A combined first principles and Mohr-Coulomb criterion for the determination of the nanohardness of amorphous silicon

Although, the evaluation of the nanohardness of amorphous silicon (a-Si) has been the subject of a few experimental works but, to date, it has not been addressed theoretically yet.In this work, first principles Kohn-Sham density functional theory (DFT)-based molecular dynamics (MD) in combination with Mohr-Coulomb criterion is employed to calculate

Comparison of designing simple steel frame & coaxial brace systems by contrast of blast, using two methods of load & resistance coefficients & performance surfaces

Nowadays, because of SLR the increasing terrorist attacks around the urban areas, designing buildings by contrast of resulted loads of blast came into consideration particularly in some sensitive buildings & vital arteries.When a blast occurs, the resulted emissions in environment leads to appearance of several penalties and endangers to the human
