A general framework is presented for evaluating stress triaxiality fields using five different configurations of Dirichlet boundary conditions. The latter ones were measured via stereocorrelation a simple shear test on thin sample where buckling was mitigated with an anti-buckling fixture. Friction and material parameters displayed negligible influence the fields. Accounting fixtures provided m...

It is dealt with the question, under which circumstances the canonical Noether stress-energy tensor is equivalent to the gravitational (Hilbert) tensor for general matter fields under the influence of gravity. In the framework of general relativity, the full equivalence is established for matter fields that do not couple to the metric derivatives. Spinor fields are included into our analysis by...

Cellular stress response proteins like Hsp70 may be affected by exposure to static magnetic fields (SMF). We examined whether exposure to a 100 mT SMF and GSH-depleting diethymaleate (DEM) would affect the levels of Hsp70 mRNA in HL-60 cells. Cells were exposed to SMF, DEM, a combination of DEM and SMF as well as 42oC. We found that only exposure to 42oC significantly affected the levels of Hsp...

In this paper, the interface crack of two non-homogenous functionally graded materials is studied. Subsequently, with employing the displacement method for fracture of mixed-mode stress intensity factors, the continuous variation of material properties are calculated. In this investigation, the displacements are derived with employing of the functional graded material programming and analysis o...

conclusions stress had a moderate level in dental students of study, which requires more attention. due to the most level of stress in students of fifth and sixth years, it is recommended to take specific actions for this sensitive period of dentistry education. background studying dentistry environment is important to assess stress causes, which is harmful for educational system. objectives th...

in this paper, stress and displacement fields of functionally graded (fg) nanocomposite cylinders reinforced by carbon nanotubes (cnts) subjected to internal pressure and in thermal environment are investigated by finite element method. the nanocomposite cylinders are combinations of single-walled carbon nanotubes (swcnts) and isotropic matrix. material properties are estimated by a micro mecha...
