Thermo-Elasto-Plastic analyses of thick-walled spherical tanks made of functionally graded materials are investigated analytically. These tanks are subjected to positive or negative temperature gradient and internal pressure loadings separately or simultaneously. The power law modeling has been used for through-the-thickness variation of mechanical properties. von Mises yield criterion and Elas...

The behavior of an exponentially graded hybrid cylindrical shell subjected to an axisymmetric thermo-electro-mechanical loading placed in a constant magnetic field is investigated. The hybrid shell is consisted of a functionally graded host layer  embedded with pyroelectric layers as sensor and/or actuator  that can be imperfectly bonded to the inner and the outer surfaces of a shell. The shell...

The synergistic effects of reactive polyol diluent and amino-functionalized multi-walled carbon nano-tubes on fracture of two-and three-phase (hybrid) epoxy nanocomposites are investigated under quasi-static and dynamic loading conditions. Digital image correlation method with a drop-tower and high-speed camera are used for dynamic tests. The crack-tip deformation histories and fracture paramet...

present paper is devoted to stress and deformation analyses of heated variable thickness functionally graded (fg) circular plate with clamped supported, embedded on a gradient elastic foundation and subjected to non-uniform transverse load. the plate is coupled by an elastic medium which is simulated as a winkler- pasternak foundation with gradient coefficients in the radial and circumferential...

Abstract Martensitic phase transformation and plasticity are two primary mechanisms of deformation in shape memory alloys (SMAs) the interaction between them influences behaviour SMA during cyclic loading, specifically pseudoelasticity effect. This interaction, which occurs microscale, affects reversibility eventually actuation capacity SMAs. In order to capture this a discrete dislocation–tran...

This paper deals with magneto-thermo-elastic interaction due to thermal shock on the stress free boundary of the half-space of perfect conducting medium in the context of two-temperature generalized thermo-elasticity with energy dissipation (TEWED) (GN III model), see [1, 2, 3]. The governing equations are solved in the Laplace transformation domain using state-space approach. The inversion of ...

A smart method, a combination of finite element and machine learning techniques, has been developed to predict the thermo-mechanical responses architectured ceramics as described in article, number 2201408, by Hamidreza Yazdani Sarvestani, Mikko Karttunen, Behnam Ashrafi, co-workers. The strategy is able find high-performance subjected various loading with reduced computational cost. These mate...

Novel mixed antioxidants composed of antioxidant IPPD and lanthanum (La) complex were added as a filler to form natural rubber (NR) composites. By mechanical testing, Fourier transform infrared spectroscopy with attenuated total reflectance (FTIR-ATR) and thermogravimetric analysis (TGA), a string of data, including the mechanical properties, the variation of internal groups and the thermal and...
