cold rolling process of a major transformation in the form of sheet metal and a wide range of steel products are produced in this way. elastic deformation during cold rolling working rollers and the inevitable increase in the rolling force. in this study, the effect of elastic deformation during cold rolling mill rollers working on the reciprocating back and forth in tandem with the presence of...

in this paper, the radial breathing mode (rbm) frequencies of multi-walled carbon nanotubes (mwcnts) are  obtained based on the multiple-elastic thin shell model. for this purpose, mwcnt is considered as a multiple concentric elastic thin cylindrical shells, which are coupled through van der waals (vdw) forces between two adjacent tubes. lennard-jones potential is used to calculate the vdw forc...

In the present study normal plate-impact experiments are conducted to investigate the propagation of acceleration waves in 2-D layered material systems. The objective of these experiments is to understand the role of material architecture and material inelasticity in controlling precursor decay and late-time dispersion of acceleration waves in elastic-elastic and elasticviscoelastic laminates. ...

In this article on increasing the efficiency of steel combined structures, tasks rational design, regulation and control structural parameters elements, use steels with increased mechanical properties are considered. It is shown that for a six-span stiffening girder truss elastic supports, which operates under distributed load, moment 72 times smaller than single-span beam. suggested to high-st...

Motivated by the increased interest in modeling nondissipative materials constitutive relations more general than those from Cauchy elasticity, we initiate study of a class stretch-limited elastic strings: string cannot be compressed smaller certain length less its natural nor elongated larger greater length. In particular, consider equilibrium states for suspended between two points under forc...

The excitation function of proton elastic scattering from $^{10}\mathrm{Be}$ at keV energy is calculated using the method self-consistent Skyrme Hartree-Fock in continuum. calculation successfully reproduces narrow near-threshold proton-emitting resonance (${E}_{x}=11.4$ MeV, $\mathrm{\ensuremath{\Gamma}}=6$ keV, and quantum number ${J}^{\ensuremath{\pi}}=1/{2}^{+}$) $^{11}\mathrm{B}$ relevant ...

We explore the structure of ground state $^{20}\mathrm{Ne}$ by investigating various density profiles. Four candidates for configurations, (a) $j\text{\ensuremath{-}}j$ coupling and (b) SU(3) shell model (c) $5\ensuremath{\alpha}$ (d) $^{16}\mathrm{O}+\ensuremath{\alpha}$ cluster are generated utilizing antisymmetrized quasicluster model. A high-energy reaction theory, Glauber model, relates th...

Since the ventricular myocardium is made up of a band of myocardial fibres which are configured into a complicated three-dimensional helical way, some time spent handling and observing this teaching model can help any cardiologist involved in imaging methods to understand and interpret the structural basis of the motion patterns of the heart. We concede that we need the cooperation of all disci...

Polymer-clay nano-composite materials, in which nano-meter thick layers of clay dispersed in polymer matrix, have generally higher mechanical properties than normal polymeric materials. A new three-dimensional unit cell model has been developed for modeling three constituent phases including inclusion, interphase and matrix. The total elastic modulus of nano-composite is evaluated.  Numerical r...

Martensite is a supersaturated solid solution of carbon in body-centered iron wherein interstitial atoms preferentially occupy single octahedral sublattice. Despite century research, the mechanism this long-range ordering still subject debate. Recently, Zener’s theory was challenged both experimentally and theoretically. In an attempt to settle controversy, we investigated by density functional...
