The refined theory of beams, which takes into account both rotary inertia and shear deformation, was developed jointly by Timoshenko and Ehrenfest in the years 1911-1912. In over a century since the theory was first articulated, tens of thousands of studies have been performed utilizing this theory in various contexts. Likewise, the generalization of the Timoshenko-Ehrenfest beam theory to plates was given by Uflyand and Mindlin in the years 1948-1951.The importance of these theories stems from the fact that beams and plates are indispensable, and are often occurring elements of every civil, mechanical, ocean, and aerospace structure.Despite a long history and many papers, there is not a single book that summarizes these two celebrated theories. This book is dedicated to closing the existing gap within the literature. It also deals extensively with several controversial topics, namely those of priority, the so-called 'second spectrum' shear coefficient, and other issues, and shows vividly that the above beam and plate theories are unnecessarily overcomplicated.In the spirit of Einstein's dictum, 'Everything should be made as simple as possible but not simpler,' this book works to clarify both the Timoshenko-Ehrenfest beam and Uflyand-Mindlin plate theories, and seeks to articulate everything in the simplest possible language, including their numerous applications.This book is addressed to graduate students, practicing engineers, researchers in their early career, and active scientists who may want to have a different look at the above theories, as well as readers at all levels of their academic or scientific career who want to know the history of the subject. The Timoshenko-Ehrenfest Beam and Uflyand-Mindlin Plate Theories are the key reference works in the study of stocky beams and thick plates that should be given their due and remain important for generations to come, since classical Bernoulli-Euler beam and Kirchhoff-Love theories are applicable for slender beams and thin plates, respectively.Related Link(s)

This book is the proceeding of the International Conference on Sustainable Engineering Development and Technological Innovation (ICSEDTI 2022) that was successfully held on 11-13 October 2022 using an hybrid platform. The conference is themed “Sustainable empowerment of innovative solutions through the development of integrated scientific researches to enhance the advanced technological world”, which represents our belief of how the sustainability is essential in our approach to solve problems through technological innovation. A total of 56 papers were submitted and presented within the sessions of the conference. The papers’ topics revolve around Informatics Technology, Electrical Technology, Marine Technology, Manufacturing System and Technology, Mechanical Engineering, And also Information Industry and Management. In addition to the technical paper presentations, there were also five keynote speeches featured, and eight plenary talks were delivered. Two of the keynote speeches were delivered in person by Professor Selo from Universitas Gajah Mada, Indonesia, and Professor Goib Wiranto from the National Research and Innovation Agency, Indonesia. The rest of the keynote speeches were delivered online by Professor Yvon Kermarrec from IMT Atlantique, France; Professor Ian Gibson from University of Twente, Netherlands; and Dr. Ilham Akbar Habibie from The Association of Indonesian Engineer, Indonesia. It was a great pleasure to work with the technical program committee led by Mr. Hilfi Pardi, who have completed the imperative process of peer-review on the technical papers submitted in this conference. We are also very fortunate to have on our side the excellent organizing committee team of the Faculty of Engineering of UMRAH who work very hard to organize and support the conference. Finally, our appreciation to all the authors who have participated in this conference with their amazing achievements and enthusiasm. We firmly believe that ICSEDTI is a suitable platform for researchers, engineers, and developers who are concerned with sustainability in engineering and technological development. We hope in the coming years ICSEDTI will be better in terms of the organization of the conference, the quantity and the quality of the researches submitted, and most importantly the impact on the sustainability of technological innovation.

We present the 53rd volume of the "International Journal of Engineering Research in Africa" to our readers. This volume contains the articles reflecting the research results in the fields of structural alloys, applied mechanics and mechanical engineering, assessment of the potential efficiency of use the cleaner electricity generation, materials and technologies in construction, biofuel production and chemical treatment of the industrial wastewater, remote sensing, and industrial engineering. The articles will be useful for many engineers as well as for academic teachers and students majoring in the mentioned fields of engineering science.

In the last decade, due to factors of ICT infrastructural and broadband maturation, rising levels of educational attainment and computer literacy, and diversification strategies, e-learning has exploded in the Middle East and North Africa (MENA) region. However, significant barriers remain in the region’s e-learning development: lack of research on outcomes and effectiveness, paucity of Arabic language learning objects, monopolies and high cost of telecommunications, cultural taboos, accreditation, censorship, and teacher training. This unique volume is the first comprehensive effort to describe the history, development, and current state of e-learning in each of the 20 MENA countries from Algeria to Yemen. Each entry is expertly written by a specialist who is acutely familiar with the state of e-learning in their respective country, and concludes with a bibliography of key reports, peer-reviewed books and articles, and web resources. E-Learning in the Middle East and North Africa (MENA) proves itself as a vital compendium for a wide readership that includes academics and students, transnational program directors, international education experts, MENA government departments, commercial vendors and investors, and ICT development and regulatory agencies involved in e-learning in the Middle East.

The definitive guide to unsaturated soil— from the world's experts on the subject This book builds upon and substantially updates Fredlund and Rahardjo's publication, Soil Mechanics for Unsaturated Soils, the current standard in the field of unsaturated soils. It provides readers with more thorough coverage of the state of the art of unsaturated soil behavior and better reflects the manner in which practical unsaturated soil engineering problems are solved. Retaining the fundamental physics of unsaturated soil behavior presented in the earlier book, this new publication places greater emphasis on the importance of the "soil-water characteristic curve" in solving practical engineering problems, as well as the quantification of thermal and moisture boundary conditions based on the use of weather data. Topics covered include: Theory to Practice of Unsaturated Soil Mechanics Nature and Phase Properties of Unsaturated Soil State Variables for Unsaturated Soils Measurement and Estimation of State Variables Soil-Water Characteristic Curves for Unsaturated Soils Ground Surface Moisture Flux Boundary Conditions Theory of Water Flow through Unsaturated Soils Solving Saturated/Unsaturated Water Flow Problems Air Flow through Unsaturated Soils Heat Flow Analysis for Unsaturated Soils Shear Strength of Unsaturated Soils Shear Strength Applications in Plastic and Limit Equilibrium Stress-Deformation Analysis for Unsaturated Soils Solving Stress-Deformation Problems with Unsaturated Soils Compressibility and Pore Pressure Parameters Consolidation and Swelling Processes in Unsaturated Soils Unsaturated Soil Mechanics in Engineering Practice is essential reading for geotechnical engineers, civil engineers, and undergraduate- and graduate-level civil engineering students with a focus on soil mechanics.
