We have used high-energy x-ray scattering to map the strain fields around crack tips in fracture specimens of a bulk metallic glass under load at room temperature and below. From the measured strain fields we can calculate the components of the stress tensor as a function of position and determine the size and shape of the plastic process zone around the crack tip. Specimens tested at room temp...

for dynamic analyses of railway track structures, the algorithm of solution is very important. for estimating the important problems in the railway tracks such as the effects of rail joints, rail supports, rail modeling in the nearness of bridge and other problems, the models of the axially beam model on the elastic foundation can be utilized. for studying the effects of axially beam on the ela...

Density functional theory with a gradient PBE and dispersion correction D3(BJ) in the basis of localized orbitals CRYSTAL17 package was used to study effect pressure on structural, electronic, elastic properties K 2 Ca(CO 3 ) , Mg(CO Na Ca (CO . The parameters third-order Birch--Murnaghan equation state are determined, it is shown that equilibrium volume compressibility modulus depend linearly ...

A dispersion of stiff and thin (‘rigid line’) inclusions (RLIs) in a matrix material may result beneficial for stiffening the elastic range, but might be detrimental to strength, as instabilities triggered by when is brought viscoplastic-damaging state. This dual role RLIs investigated means embedded reinforcement model. Validated against available analytical predictions, this numerical model e...
