The study develops the displacement error recovery method in a mesh free environment for finite element solution employing radial point interpolation (RPI) technique. RPI technique uses basis functions (RBF), along with polynomials to interpolate fields node patch and recovers field. global local errors are quantified both energy L2 norms from post-processed considers multi-quadrics/gaussian/th...

Delamination is one of the most common failure modes in composite structures. In particular, when the laminated composites are subjected to compressive loads, delamination becomes a constraint in the design process. In this study, the system is modeled as a plate supported by an elastic foundation. The elastic adhesive layer between the buckled sublaminates is represented by some parallel sprin...

the high blood rate that often occurs in arteries may play a role in artery failure and tortuosity which leads to blackouts, transitory ischemic attacks and other diseases. however, vibration and instability analysis of carotid arteries are lacking. the objective of this study is to investigate the vibration and instability of the carotid arteries conveying blood under axial tension with surrou...

The stacking of impermissible materials in the disposal dry fly ash is unprecedented last 40 years power plant management China, and their effect on stability whole facility uncertain. Due to lack relevant treatment experience, a more comprehensive method such as numerical modeling must be adopted for final design. This paper set up borehole database from geological logging data obtain distribu...

in present study, thermo-elastic buckling analysis of multi-layer orthotropic annular/circular graphene sheets is investigated based on eringen’s theory. the moderately thick and also thick nano-plates are considered. using the non-local first and third order shear deformation theories, the governing equations are derived. the van der waals interaction between the layers is simulated for multi-...

in this paper, the effects of carbon nanotube (cnt) orientation and aggregation on the static behavior of functionally graded nanocomposite cylinders reinforced by cnts are investigated based on a mesh-free method. the used nanocomposites are made of the straight cnts that are embedded in an isotropic polymer as matrix. the straight cnts are oriented, randomly or aligned or local aggregated int...
