the flow stress of steel depends significantly on microstructural changes taken place during hot deformation processes. in hot deformation processes, the flow stress of steel is influenced by two main metallurgical phenomena, i.e. recovery and recrystallization, along with its chemical composition and thermo-mechanical parameters. the final mechanical properties of steel are also determined by ...

The description of the behavior a material subjected to multi-physics loadings requires formulation constitutive laws that usually derive from Gibbs free energies, using invariant quantities depending on considered physics and symmetries. On other hand, most crystalline materials can be described by their texture associated preferred directions strong symmetry (the so-called fibers). Moreover, ...

We report on a versatile experimental setup for the study of electro-magneto-elasto-thermal coupling bulk materials having properties. The enables measurement stress and electrical resistivity in 80-450 K temperature range under controlled uniaxial pressure magnetic field up to 8 T. strong influence strain transport properties is shown Ni-Co-Mn-In Heusler single crystal material. Phase transfor...

In this article, the magneto-thermo-elastic problem of exponentially graded material (EGM) hollow rotating disk placed in uniform magnetic and temperature fields is considered. Exact solutions for stresses and perturbations of the magnetic field vector in EGM hollow rotating disk are determined using the infinitesimal theory of magneto-thermo-elasticity under plane stress. The material properti...

In this study, the vibration behavior of functional graded (FG) circular and annular nanoplate embedded in Visco-Pasternak foundation and coupled with temperature change is studied. It is assumed that a uniform radial magnetic field acts on the top surface of the plate and the magnetic permeability coefficient of the plate along its thickness are assumed to vary according to the volume distribu...

The present investigation deals with the deformation in micropolar generalized thermoelastic medium with mass diffusion subjected to thermo mechanical loading due to thermal laser pulse. Laplace and Fourier transform technique is used to solve the problem. Concentrated normal force and thermal source are taken to illustrate the utility of approach. The closed form expressions of normal stress, ...
