In this paper, a matrix equation method, a dimension-reduce then dimension-increase matrix method is proposed to model leverage structure and closed-loop structure of compliant mechanism, respectively. The accuracy of the methods is validated by finite-element analysis (EFA).
Designing nanoplasmonic devices presents a number of unique challenges. The time domain modelling and simulation of electromagnetic (EM) wave interaction with nanoplasmonic devices, at high spatial and time resolution, requires high computational power. Recent advances in commodity hardware technologies, particularly multi-core CPU, field-programmable gate arrays (FPGAs) and graphic processing units...
In this work, a hybrid finite element volume FEV method is further extended to simulate soot nanoparticles formation and oxidation in a heavily sooting co-flow methane diffusion flame at elevated pressure. In this regard, two-equation soot model is used and soot oxidation due to O2 is further taken into account. Considering full soot oxidation and respecting the physics of the flow, physical upwinding...
This paper describes the simulation of the phenomenon of nucleation of the precipitate Al3Sc in an Aluminum Scandium alloy using the kinetic Monte Carlo (kMC) method and the density-based clustering with noise (DBSCAN) method to filter the simulation data. To conduct this task, kMC and DBSCAN algorithms were implemented in C language. The study covers a range of temperatures, concentrations, and dimensions,...
Though thermal conductivity of single walled carbon nanotubes has been intensively studied, the quantum correction method for the temperature dependence of thermal conductivity of the tube and phonon density of states (DOS) for different boundary conditions have been discussed very rarely. In this paper, we studied the tube ends constrained model for thermal conductivity calculation, and a simple...
This paper intends to study the phenomena of thermal-caused material modifications in the principle of nanoscale electro spark during the SPM-based electric lithography. Since the direct observation of the electro spark process seems impossible in the nanoscale gap region, the molecular dynamics (MD) simulation method is applied to help investigate the influence of the thermal effect due to the Joule...
nanoHUB.org is arguably the largest online nanotechnology user facility in the world. From an initial user base of about 1,000 users, nanoHUB has grown to support over 250,000 users annually. nanoHUB supports users in 172 countries with materials for research and education, along with a wide variety of simulation tools covering many nano-related areas. Preliminary assessments of user behavior patterns...
