Special Issue Information

Dear colleagues,

The continuous development of novel composite materials with increased mechanical performances and low density has encouraged the adoption of different components, such as functionally graded materials (FGMs), carbon nanotubes (CNTs), graphene nanoplatelets, or SMART constituents for many practical engineering applications, e.g., biomedicine, aerospace facilities, automotive industry, energy devices, and civil applications.

In a context where the recent requirements in design and manufacturing have led to an increased development of nanoshells, carbon nanotubes, and paramagnetic nanoparticles, this Special Issue aims at gathering together experts and young researchers for the mechanical modeling of materials and structures in the small-scale range. The physical and mechanical properties of small-scale structures are well known to be size-dependent. This represents a key aspect, largely explored both theoretically and computationally by means of advanced nonlocal approaches. These are here explored to handle both the continuum solid mechanics and fracture mechanics, for which the nonlocal aspect is a requisite for a realistic description of fracture, including the crack inception or propagation and the structural size effect related to the existence of a finite size fracture process zone. Advanced theories and high-performance computational modeling on the statics or dynamics of nano-systems and nano-structures are welcome, together with the development of enhanced nonlocal damage and fracturing models, able to capture the formation and propagation of the internal cracks related to the heterogeneity of complex materials and interfaces.

Buckling Behavior of Nanobeams Placed in Electromagnetic Field Using Shifted Chebyshev Polynomials-Based Rayleigh-Ritz Method
Nanomaterials 2019, 9(9), 1326; https://doi.org/10.3390/nano9091326 - 16 Sep 2019
Abstract
In the present investigation, the buckling behavior of Euler–Bernoulli nanobeam, which is placed in an electro-magnetic field, is investigated in the framework of Eringen’s nonlocal theory. Critical buckling load for all the classical boundary conditions such as “Pined–Pined (P-P), Clamped–Pined (C-P), Clamped–Clamped (C-C), [...] Read more.
In the present investigation, the buckling behavior of Euler–Bernoulli nanobeam, which is placed in an electro-magnetic field, is investigated in the framework of Eringen’s nonlocal theory. Critical buckling load for all the classical boundary conditions such as “Pined–Pined (P-P), Clamped–Pined (C-P), Clamped–Clamped (C-C), and Clamped-Free (C-F)” are obtained using shifted Chebyshev polynomials-based Rayleigh-Ritz method. The main advantage of the shifted Chebyshev polynomials is that it does not make the system ill-conditioning with the higher number of terms in the approximation due to the orthogonality of the functions. Validation and convergence studies of the model have been carried out for different cases. Also, a closed-form solution has been obtained for the “Pined–Pined (P-P)” boundary condition using Navier’s technique, and the numerical results obtained for the “Pined–Pined (P-P)” boundary condition are validated with a closed-form solution. Further, the effects of various scaling parameters on the critical buckling load have been explored, and new results are presented as Figures and Tables. Finally, buckling mode shapes are also plotted to show the sensitiveness of the critical buckling load. Full article

Evaluating the mechanical ability of nanofibrous membranes during processing and end uses in tissue engineering is important. We propose a geometric model to predict the uniaxial behavior of randomly oriented nanofibrous membrane based on the structural characteristics and tensile properties of single nanofibers. Five types of silk fibroin (SF)/poly(ε-caprolactone) (PCL) nanofibers were prepared with different mixture ratios via an electrospinning process. Stress–strain responses of single nanofibers and nanofibrous membranes were tested. We confirmed that PCL improves the flexibility and ductility of SF/PCL composite membranes. The applicability of the analytical model was verified by comparison between modeling prediction and experimental data. Experimental stress was a little lower than the modeling results because the membranes were not ideally uniform, the nanofibers were not ideally straight, and some nanofibers in the membranes were not effectively loaded.

Detwinning Mechanism for Nanotwinned Cubic Boron Nitride with Unprecedented Strength: A First-Principles Study

Synthesized nanotwinned cubic boron nitride (nt-cBN) and nanotwinned diamond (nt-diamond) exhibit extremely high hardness and excellent stability, in which nanotwinned structure plays a crucial role. Here we reveal by first-principles calculations a strengthening mechanism of detwinning, which is induced by partial slip on a glide-set plane. We found that continuous partial slip in the nanotwinned structure under large shear strain can effectively delay the structural graphitization and promote the phase transition from twin structure to cubic structure, which helps to increase the maximum strain range and peak stress. Moreover, ab initio molecular dynamics simulation reveals a stabilization mechanism for nanotwin. These results can help us to understand the unprecedented strength and stability arising from the twin boundaries. Full article
