Professor Shaker Meguid obtained his PhD in Applied Mechanics from UMIST, England. He taught different branches of Applied Mechanics in 4 continents, including Oxford University, Cranfield University (England), University of Toronto, Cairo University (Egypt) and Nanyang Technological University (NTU-Singapore). His research activities have contributed significantly to the areas of nanoengineering, computational mechanics, advanced and smart composites, fracture mechanics and failure prevention. He has published over 400 papers in leading tier-1 scientific journals and international conferences and symposia including the most recently the 4th International Conference on Integrity, Reliability and Failure in June 2013. He not only organised but also contributed to numerous symposia as keynote and plenary speaker. He is the founding Editor-in-Chief of the International Journal of Mechanics and Materials in Design, Guest Editor to a number of Journals, Former Technical Associate Editor, for two consecutive terms, of ASME Journal of Engineering Materials and Technology, and a member of the editorial board of numerous journals. He is also the Editor of six international conference proceedings and author of two textbooks. Professor Meguid is the founding head of the Aerospace Division of NTU, Singapore. He holds the titles of Distinguished Visiting Professor in Tongji University (China), Porto University (Portugal), external examiner to Dublin Institute of Technology (Ireland), University of Putra Malaysia (Malaysia), and an Engineering Consultant to the United Nations. He is a lifetime member of AIAA, member of the American Academy of Mechanics, Professional Engineer in the Province of Ontario (P.Eng.), Chartered Engineer in Great Britain (CEng), Fellow of the American Society of Mechanical Engineers (ASME), and Fellow of IMechE. He works closely with the aerospace and automotive industries and is regularly approached by members of the media for clarification of engineering issues. Professor Meguid and his students have won many awards including the recent innovation award in nanoengineering by ASME. Professor Meguid is currently hosted by Peking University as Globex Fellow to teach Mechanics of Solids under the Global Exchange Program.

Professor Jasiuk studies engineering and biological materials. She investigates materials theoretically and experimentally and designs new advanced materials based on bioinspiration for various medical and technological applications. The engineering materials of interest include composites and nanocomposites, polymers, and alloys for aerospace, automotive, and energy applications. The biological materials studies address the mechanics of bone and hoof. She is also designing new bioinspired materials and 3D printing them using various additive manufacturing techniques. A project on bone aims to explain the mechanics of bone at different structural scales to obtain predictive tools for healthy and diseased bone. She is also exploring computational and non-invasive experimental tools for use in clinical settings to diagnose bone health. A project on natural materials investigates a hoof wall and hoof-inspired materials. Professor Jasiuk is studying, jointly with Professor Marc Meyers from the University of California at San Diego, the hoof wall's structure, composition, and mechanical properties at different structural levels. They are also designing hoof-inspired impact-resistant materials for various engineering applications. The National Science Foundation (NSF) sponsors this project. In a third project, she develops, manufactures, characterizes, and models novel architectured cellular bioinspired multifunctional materials. She employs different additive manufacturing techniques to create models for testing and investigates their mechanical, electrical, thermal, acoustic, and electromagnetic properties. Another project addresses novel composite materials and structures for marine turbine blades for energy harvesting with Dr. Leo Chamorro, ATSP Innovations, and the University of New Hampshire. Department of Energy supports this project. Finally, Professor Jasiuk has been a site director of the NSF I/UCRC Center on Novel High Voltage/Temperature Materials and Structures. She designs and explores novel high-temperature composite and nanocomposite materials for aerospace applications and high-conductivity alloys for power transmission.
EFM covers a broad range of topics in fracture mechanics to be of interest and use to both researchers and practitioners. Contributions are welcome which address the fracture behavior of conventional engineering material systems as well as newly emerging material systems. Contributions on developments in the areas of mechanics and materials science strongly related to fracture mechanics are also welcome. Papers on fatigue are welcome if they treat the fatigue process using the methods of fracture mechanics.
In continuum fracture mechanics, it is well established that interactions of micro-cracks and voids with the crack can significantly alter the stress concentration around the crack tip.44,45 However, atomistic studies on multiple crack interaction are quite limited. Liu et al.46 investigated the crack void interaction in α-Fe and Dewapriya et al. showed that lattice trapping of graphene can be achieved by placing holes and multiple cracks around the crack tip.47,48 However, to the best of our knowledge, no such study has been conducted to provide any solution to increase the mechanical properties of silicene nanosheet containing pre-existing crack.
