“…AM process parameters control the solidification process and the mechanical properties [3,[5][6][7][8][9][10][11][12]. The mechanical properties of materials can be simulated using their microstructures [13][14][15][16][17][18][19][20]. However, as in AM, the microstructure is a function of process parameters, and it would be beneficial to find a direct relationship between the AM process parameters and their mechanical properties.…”

Additive manufacturing (AM) method has attracted huge interest in the past decade due to its ability in building complicated geometries with a much lower cost than conventionally produced parts. In AM, which the part is produced in a layer by layer manner, by controlling the AM process parameters, the final mechanical properties can be controlled. In other words, the AM process parameters define the amount of energy that is transferred into the powder, which has a direct relationship with the final mechanical properties. The amount of energy for any sets of AM process parameters affects the melt pool geometry. In this study, the correlation between melt pool geometry and mechanical properties of selective laser melted (SLM) Ti-6Al-4V samples is investigated

“…14 It is worthwhile to mention that these nanomaterials, with promising properties, e.g., remarkable thermal conductivity and tensile strength as well as high spring constant, are classified as the efficient elements of micro-nanoelectrochemical devices, 15 nanomotors, 16,17 artificial muscles, 18 etc. Moreover, as a common application, they play a pivotal role as reinforcing agents in nanocomposites to improve thermal and mechanical properties 19,20 as well as hydrogen storage. 21 Based on the desired features of carbon nanomaterials, novel spiral structures were produced gradually in a manner inspired by nature, such as coiled carbon nanotubes (CCNTs) and graphene helicoids (GHs).…”

The ever-increasing need for miniaturization of electromechanical devices has led us to exploit the properties of nanomaterials as well as controlling them. Chemical doping is one of the most commonly used techniques for controlling the properties of nanomaterials. Spiral carbon-based nanostructures possess excellent electrical properties, which are highly improved with chemical doping; however, the effect of chemical doping on their mechanical properties is still unknown. In this study, molecular dynamics simulation is conducted to study the effect of random/patterned boron and nitrogen doping in different percentages on the mechanical properties of spiral carbon-based nanostructures. The results show a significant impact of the geometry on the mechanical response of doped spiral nanostructures. Furthermore, increasing the percentage of the chemical doping influences the mechanical behavior of these nanoparticles, which can reduce their extensive stretchability even up to 50%. Chemical doping at the position of the pentagon/heptagon defects of nanostructures has led to interesting mechanical behavior in addition to electrical properties. Thus, using a combination of a couple of methods such as chemical doping and changing the geometry of the spiral carbon-based nanostructures opens a new avenue to control the properties of these nanostructures in proportion to their electromechanical applications.

This paper presents three-dimensional finite element modeling of nanocomposite materials made from polyethylene polymer reinforced by coiled carbon nanotubes. A method of Python scripting was used to generate representative volume elements in order to determine the mechanical behavior in elastic and plastic zones as well as effective thermal conductivity using the finite element software. The properties of the nanocomposites are investigated by considering the interphase zone between carbon nanofillers and matrix. The effects of different volume fractions, geometrical parameters, and orientations of the nanofillers on the elastic and thermal characteristics of the nanocomposites are studied considering both cohesive interaction and perfect bonding between the fillers and matrix. Moreover, the effects of applying strain on the effective thermal conductivity of the representative volume elements are analyzed. The results reveal that both stress–strain curves and thermal conductivity coefficients of the nanocomposites are following similar trends vs. the changes of the volume fractions as well as the geometries and orientations of the coiled carbon nanotubes. Analysis of the tensile toughness of all samples reveals that it is affected by both stress and the number of fillers in the representative volume element. In addition, thermal-displacement analysis shows that thermal conductivity coefficient decreases by increasing the applied strain on the representative volume element, while the intensity of decrease of the nanocomposite thermal conductivity depends on the volume fraction and interaction of the nanofillers and interphase zone. Finally, crashworthiness analysis of the nanocomposite material proves that they are appropriate candidates for absorbing energy under impact loadings in comparison to metals.
