[ 1 ] - The Effects of Carbon Nanotube Orientation and Aggregation on Static Behavior of Functionally Graded Nanocomposite Cylinders
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...
[ 2 ] - A New Numerical Procedure for Determination of Effective Elastic Constants in Unidirectional Composite Plates
In this paper a composite plate with similar unidirectional fibers is considered. Assuming orthotropic structure, theory of elasticity is used for investigating the stress concentration. Also, complex variable functions are utilized for solving the plane stress problems. Then the effective characteristics of this plate are studied numerically by using ANSYS software. In this research a volume e...
[ 3 ] - تحلیل ابعادی شکل دهی سازه نیم کُروی از آلیاژ تیتانیوم 4-6، به روش هیدرواستاتیک-سوپرپلاستیک
Experimental tests on superplastic forming of alloy Ti-6Al-4V with large dimensions can be quite difficult and expensive. In order to avoid the expense of manufacturing alloy sections, numerical modelling is used to simulate the alloy’s superplastic behaviour. However the results obtained from the numerical modelling need to be verified against experimental tests. In order to reduce the expense...
