Chan Nano-sized, nonreacting, noncoarsening Al2O3 particles have been incorporated into eutectic Sn–Zn solder alloys to investigate the microstructure, hardness and shear strength on Au/Ni metallized Cu pads ball grid...

in this paper, the effect of different boundary conditions on the free vibration analysis response of a sandwich plates is presented using higher order shear deformation theory. the face sheets are orthotropic laminated composite that follow the first order shear deformation theory (fsdt) based on rissners-mindlin (rm) kinematics field. based on energy method and hamilton's principle, the ...

rheological characteristics of al2o3, cuo and tio2 nano particles were investigated in oil asthe base fluid at 1 and 2 wt.%. constitutive relations for non-newtonian fluid were discussedbased on the power-law model. measured viscosities of each nanofluid were used to evaluatethe power-law and consistency index. results indicated that the nanofluid viscosity decreasedby increasing the concentrat...

Nano CuO and alkane surfactant modified phenol Formaldehyde (PF) resins were applied to manufacture plywood, and physical and mechanical properties, such as shear strength, tensile property, modulus of rupture (MOR), modulus of elasticity (MOE), as well as termite resistance were evaluated. The result showed that the combination of nano CuO and alkane surfactantplayed different effect on tensil...

Situations of contact between deformable bodies are very common in industry and everyday life such as train wheels with the rails, a shoe with the floor, tectonic plates, the car’s braking system, etc. Because of the importance of the contact problems, a considerable effort has been made in the modeling and numerical simulations, and the engineering literature concerning this topic is rather ex...

The inverse problem of real-time reconstruction of full-field structural displacements is addressed through the application of a new variational formulation leading to versatile, robust and computationally efficient inverse shell finite element analysis. Utilizing surface strain measurements from strain sensors mounted on the load-carrying structural components, the methodology enables accurate...

In this research, the rheological properties of non-Newtonian shear thickening fluid (STF) composed nano-sized solid particles have been investigated. The best conditions determined by optimizing both experimental production method and measurement system STFs. Mechanical, ultrasonic, mechanical ultrasonic mixing methods were used in STFs that silica particle (solid: aerosil) polyethylene glycol...
