Preface to the Special Issue on the 29th Annual International Conference of the Iranian Society of Mechanical Engineers (ISME2021)

Abstract

In this Special Issue, some selected and extended contributions, which were presented at the 29th Annual International Conference of the Iranian Society of Mechanical Engineers (ISME), held in Tehran, Iran in May 2021, are collected. Ever since the first conference in 1992, ISME conferences have been a big scientific festivity for mechanical community in Iran. The ISME conference covers a wide range of mechanical fields in science and technology and aims to bring together various engineering mechanics expertise. The ISME2021 organizers decided to bring out papers presented at the conference in the field of microand nano-mechanics as a special issue of Journal of Nanomaterials, Nanoengineering and Nanosystems. This Special Issue contains four papers and each paper has undergone a rigorous review process. In the following, the articles are briefly introduced. In one of the papers, the static behaviors of functionally graded arbitrary straight-sided quadrilateral nanoplates have been investigated on the basis of a continuum mechanics-based surface elastic model. Mechanical response of polyester based composites filled with carbon black has been studied by experimental and micromechanical methods in another paper. The influence of shear deformation on wave propagation in periodic lattices with various topologies has been examined in one of the selected papers. Finally, a novel nanocomposite bone scaffold has been fabricated and its mechanical properties have been studied by using experimental techniques and finite element method. It is hoped that readers will find the special issue interesting. We would like to thank the authors for submitting their valuable works to the Special Issue, and the anonymous reviewers for their time, effort, and professional comments in evaluating the papers. In addition, our special thanks to the editor-in-chief of the journal, Prof. Vasileios Koutsos, for his excellent cooperation.
