Study on process parameter optimization for electron beam melting additive manufacturing by Wang, Chengcheng

“…Electron beam melting additive manufacturing (EBM-AM), also known as selective electron beam melting (SEBM), is a mainstream metal additive manufacturing (AM) technique that employs an electron beam to process metallic powder feedstocks in vacuum environment (~ 10-4 - 10-5 mbar) at elevated temperatures (~ 500 - 1100 °C). …”

Plasmon excitation on flat graphene by s-polarized beams using four-wave mixing by Tao, Jin, Dong, Zhaogang, Yang, Joel K. W., Wang, Qi Jie

“…However, exciting plasmons on graphene effectively still remains a challenge owing to the large wave-vector mismatch between the optical beam in air and graphene plasmon. In this paper, we present a novel scheme capable of exciting graphene surface plasmons (GSPs) on a flat suspended graphene by using only s-polarized optical beams through four-wave mixing (FWM) process, where the GSPs fields were derived analytically based on the Green's function analysis, under the basis of momentum conservation. …”

Dynamic behavior of reinforced concrete beams under varying rates of concentrated loading by Adhikary, Satadru Das, Li, Bing, Fujikake, Kazunori

“…LS-DYNA, an explicit finite element program widely used for three-dimensional nonlinear transient analysis of structures, was employed in this study to provide numerical simulations of RC beams under varying loading rates. Three-dimensional finite element (FE) models of RC beams have been described and verified with the experimental results, followed by a parametric study to investigate the influence of the longitudinal reinforcement ratio, the transverse reinforcement ratio and the shear span to effective depth ratio. …”
