1. Introduction

The first Nanomaterials webinar, entitled “Advanced Mechanical Modeling of Nanomaterials and Nanostructures”, was held on Friday 16 October 2020, and chaired by Dr. Francesco Tornabene.

In recent decades, composite materials have been increasingly applied in many industries and used in many structural applications, due to their higher values of strength and stiffness, superior thermal properties, and lower levels of weights. The discovery of carbon nanotubes (CNTs) or further nano-scale derivatives of carbon, such as graphene, with their oxide, opens a new horizon in material science, and makes these advanced nano-scale materials an efficient alternative to conventional micro-size reinforcements such as carbon and glass fibers. The use of carbon-based nanofillers as a reinforcement phase in polymers enables enhanced properties within nanocomposites, namely, high stiffness, strength, toughness, hardness, heat distortion temperature, and electrical properties; in addition to a reduced processing cost due to their exclusive nanostructures.

In a context where increased computational demand is required to solve such solid mechanics problems, the webinar focused on the application of high-performing computational strategies and advanced theoretical formulations to solve similar complicated problems (i.e., static, dynamic problems, including possible thermal effects), while presenting comparatively the numerical results from several systematic investigations, useful for many engineering applications.

After an introduction from the chair, Prof. Dr. Rossana Dimitri presented her research on “High-performing numerical methods for the mechanical study of nanocomposite materials and structures”. Prof. Salvatore Brischetto followed with his presentation on “3D and advanced shell models for the analysis of single- and double-walled carbon nanotubes and nano-reinforced structures”.
