Affinity Properties of Truss Model Nodes
Strut and tie models consist of axial force members which react on one another and on external supports through nodes, i.e. they are trusses. An analysis of a truss problem is normally entered by reducing it to a line diagram of member centrelines representing the lines along which the stress resultants in the members are intended to act. When forces are concentrated in a line diagram the nodes...

متن کاملMechanical properties of copper octet-truss nanolattices
We investigate the mechanical properties of copper (Cu) octet-truss nanolattices through a combination of classical molecular dynamics (MD) simulations and theoretical analysis. The MD simulations show that Cu nanolattices with high relative density are stronger than bulk Cu, while also achieving higher strength at a lower relative density as compared to Cu meso-lattices. We demonstrate that mo...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولSimulated properties of Kagom e and tetragonal truss core panels
The finite element method has been used to simulate the properties of panels with Kagom e and tetragonal cores under compressive and shear loading. The simulation has been performed for two different materials: a Cu-alloy with extensive strain hardening and an Al-alloy with minimal hardening. It is shown that the Kagom e core is more resistant to plastic buckling than the tetragonal core under ...
