Dynamic fracture mechanics of layered materials has been gaining lots of attentions among the researchers where the layered materials are extensively used in various products and devices to improve structural performance such as strength and durability. The influence of the crack moving speed on the the stress intensity factors was a popular subject in classical elastodynamics. Among the models...

Composites of nanocellulose with layered silicates have recently emerged as a new type of composite materials offering superior strength, as well as thermal and gas barrier properties. These organic-inorganic hybrid composites with a nacre-like structure can be obtained from renewable resources and are environmentally friendly. They can potentially be presented as a serious alternative in the n...

Inspired by the layered aragonite platelet/nanofibrillar chitin/protein ternary structure and integration of extraordinary strength and toughness of natural nacre, artificial nacre based on clay platelet/nanofibrillar cellulose/poly(vinyl alcohol) is constructed through an evaporation-induced self-assembly technique. The synergistic toughening effect from clay platelets and nanofibrillar cellul...

In this paper, novel WS2/Bi2MoO6 heterostructured photocatalysts were successfully fabricated via a facile solvothermal growth method using pre-exfoliated layered WS2 nanoslices as a substrate. The structure, morphology, and optical properties of the as-prepared WS2/Bi2MoO6 samples were characterized by XRD, XPS, SEM, TEM (HRTEM), and UV-vis diffuse reflectance spectra (DRS). Results confirmed ...

With an ever increasing energy demand and environmental issues, many state-of-the-art nanostructured electrode materials have been developed for energy storage devices and they include batteries, supercapacitors and fuel cells. Among these electrode materials, L-TMD (layered transition metal dichalcogenide) nanosheets (especially, S (sulfur) and Se (selenium) based dichalcogenides) have receive...

We present a coupled finite element, Kalman filter approach to foresee impactinduced delamination of layered composites when mechanical properties are partially unknown. Since direct numerical simulations, which require all the constitutive parameters to be assigned, cannot be run in such cases, an inverse problem is formulated to allow for modeling as well as constitutive uncertainties. Upon s...

Nanocomposites of isotactic polypropylene (iPP) and date wood fiber were prepared after modification of the host matrix by reactive extrusion grafting of maleic anhydride. Chemical and mechanical treatment of date wood flour (WF) was conducted to obtain nanocrystalline cellulose. Layered silicates (clay) were partially intercalated with date wood fiber, and the modified layered silicate was use...

In this study, Finite Elements Method was used for the nonlinear analysis of reinforced concrete plates under gradually loading conditions beginning from zero load to failure load. Layered Composite Material Model was used for the modeling of reinforced concrete plates. The principles of this approach is given in “layered composites mechanics” that it was successfully applied for the nonlinear ...

Two-dimensional (2D) layered nanostructure composites are promising candidates for conducting high-performance energy conversion and environmental remediation. The construction of 2D layered composite photocatalysts can generate many unique properties that do not exist in other kinds of semiconductor composite photocatalyst, which are beneficial for photocatalytic performance enhancement, band ...
