Selective laser melting (SLM) produces a large amount of residual stress which limits its applicability. Despite the increasing number studies to understand relationship between process parameters and stress, underlying complex mechanisms are yet be understood. In this work, 3D finite element model (FEM) is established investigate during SLM. When in different ranges, behavior different. The could reason for contradictory parametric effects reported literature. magnitude effect on obtained....
Purpose High residual stress caused by the high temperature gradient brings undesired effects such as shrinkage and cracking in selective laser melting (SLM). The purpose of this study is to predict distribution effect process parameters on melted (SLMed) Inconel 718 thin-walled part. Design/methodology/approach A three-dimensional (3D) indirect sequentially coupled thermal–mechanical finite element model was developed SLMed material properties dependent were taken into account both thermal...
Ensuring the stability of surrounding rock while conducting pressure relief is key to roadway control and preventing burst. In this paper, segmented enlarged-diameter borehole destressing technology proposed. The stress distribution around analysed based on theory elasto-plastic mechanics, mechanism for boreholes studied. Secondly, effects diameter section, length space deformation were investigated. Finally, optimal drilling parameters Tangkou coal mine 6307 working face are analysed....
Lattice structures are crucial for weight reduction, and laser powder bed fusion (LPBF) is an efficient fabrication method. However, there's a notable research gap in understanding the residual deformation of LPBF-fabricated lattice structures. This study investigates three basic structures, body centre cell (BCC), face (FCC), diamond (DC), fabricated via LPBF to reveal their mechanisms. Analysis covers horizontal direction, building total deformations, unveiling complex structural...
Using first-principles calculations, we computationally designed a new two-dimensional (2D) inorganic material, Be3N2 monolayer with flat hexagonal structure similar to graphene. Good stability of the is demonstrated by its moderate cohesive energy, absence imaginary modes in phonon spectrum, and high melting point predicted molecular dynamics (MD) simulations. The direct band gap semiconductor 3.831 eV that can be effectively tuned employing an external strain. wide outstanding...
Abstract The effect of substitution Cr in 2H‐CrSe 2 by Fe and Co on its electronic, optical, magnetic properties is studied first‐principles density functional theory. Spin‐polarized semiconducting state realized CrSe substitutional doping Co, while a semimetallic obtained the moment after 4.52 μ B . On substitution, it observed that system presents metallic properties, with relatively low light absorption reflectance, good transparency. 2.71 coefficient to visible increases peak value...
Using density functional theory and nonequilibrium Green's function technique, we performed theoretical investigations on the structural transport properties of zigzag silicene nanoribbons (SiNRs) with Stone–Wales (SW) defect. The calculated formation energy is significantly lower than that graphene silicene, which implies high stability such defect in SiNRs. Negative differential resistance (NDR) can be observed within certain bias voltage range both perfect SW-defected In order to...
