Studies on welding process of Aluminium weldments shows that post-weld residual stress and deformation are influential on structure efficiency and there are different variable which affect these stresses and deformation. In this study the effect of geometrical variables and welding sequence on residual stresses and deformation in Aluminium H321 have investigated by the finite element software A...

Two-phase periodic thermo-magneto-electro-elastic composites are considered. The composite materials consisting of identical parallel cylindrical fibers periodically distributed in a matrix. Both constituents are transversely isotropic and the unit-cell has rhomboidal shape. Based on the asymptotic homogenization method, exact relations involving the in-plane effective coefficients are derived ...

In this study an analytical method is developed to obtain the response of electro-magneto-thermo-elastic stress and perturbation of a magnetic field vector for a thick-walled spherical functionally graded piezoelectric material (FGPM). The hollow sphere, which is placed in a uniform magnetic field, is subjected to a temperature gradient, inner and outer pressures and a constant electric potenti...

Thermo-elastic deformation of the machine tool due to thermal expansion components presents one biggest challenges in maintaining accuracy and product quality. The operation inevitably leads waste heat friction losses bearings guides electrical motors control cabinets. These internal sources lead inhomogeneous changing temperature fields, which also interact with ambient temperature. An interac...

Generation and dissipation of temperature-induced pore water pressure can alter the mechanical behavior characteristics soil media. Experimental observations indicate that heating/cooling cycles fabric which may result in irrecoverable deformations. Previous studies suggest contribution thermo-osmotic (non-Darcian) flow clays have a significant role thermal pressurization diffusion. Hence, this...

The thermo-elastic properties of a novel class ceramic composites based on an ultra-refractory matrix and containing short carbon fibre to provide failure tolerance thermal shock resistance were experimentally characterised numerically simulated. samples fabricated with volume fractions ranging from 5 60 vol% featured by homogeneous dispersion along the basal plane due processing route. A rando...

the aim of the paper is to analyze electro-thermo nonlinear vibration of a double-piezoelectric composite microplate-system (dpcmps) based on nonlocal piezoelasticity theory. the two microplates are assumed to be connected by an enclosing elastic medium which is simulated by pasternak foundation. both of smart composite microplates are made of poly-vinylidene fluoride (pvdf) reinforced by zigza...

Viscoelastic phase separation is characterized by the formation of a transient gel upon phase separation. A transient gel state is widely observed in complex fluids including polymer solutions, colloidal suspensions, and protein solutions, but its physical description is quite difficult due to its intrinsically nonequilibrium nature. We have modeled this transient gel state using a type of Brow...
