This work identifies the characteristics of racket design parameters that influence racket performance. It presents the finite element analysis of several designs of badminton rackets and compares them to experimental results for validation. Designing a racket requires a comprehensive understanding of racket performance characteristics. Essentially, racket performance is related to the sweet spot, which is the spot on the racket head that produces the most power and control when it strikes a shuttlecock. Determining a coefficient of restitution can help to identify the sweet spot on a racket. By analyzing several head shape designs, it becomes apparent that isometric head shape rackets produce better coefficients of restitution compared to oval and round ones. It is recommended that the racket design consist of low string tension, stiffer racket shafts and bigger head size in order to produce higher shuttlecock speed.
This book gathers papers presented at the 2019 Movement, Health & Exercise (MoHE) Conference and International Sports Science Conference (ISSC). The theme of this year’s conference was "Enhancing Health and Sports Performance by Design". The content covers (but is not limited to) the following topics: exercise science; human performance; physical activity & health; sports medicine; sports nutrition; management & sports studies; and sports engineering & technology.
In rowing, races are often won in spite of, not because of, technique, and many misconceptions still preoccupy both rowers and coaches. This book explains the facts about rowing technique and will help you to find the right way to achieve your best performance. In this new edition, comprehensively updated to take account of the most recent developments in the sport The Biomechanics of Rowing offers a unique insight into the technical and tactical aspects of rowing, based on over twenty-five years experience of working with the best rowers and coaches all around the globe, a careful analysis of millions of data samples, and comprehensive biomechanical modelling with the aim of finding an optimal balance of variables. Topics covered include measurement; performance analysis; technique; ergometer rowing and, finally, rowing equipment and rigging.
This ebook is a compilation of 234 papers presented at the 6th Asia International Conference on Tribology (ASIATRIB2018): Kuching, Sarawak - Malaysia from 17 to 20 September 2018.
The Badminton Handbook is a compact, groundbreaking training manual that gives the reader an overall insight into the world of badminton. It is divided into two parts. The first part deals with training theory while the second contains background information about the sport and its stars, thus giving the reader an overall insight into the world of badminton. The Badminton Handbook is groundbreaking in many ways. It combines training theory and information about badminton stars by reinforcing basic explanations on badminton technique with tips from the pros. It not only relates the excitement of this sport with Asian origins, but tells you all you need to know about badminton from A to Z. It is a reliable reference book that readers will want to turn to again and again.
This book presents a simplified approach to earthquake engineering by developing the fragility curve for regular and irregular moment-resisting frames based on different types of structural material, height, and ground motion records. It examines six sets of concrete and steel frames, which vary in terms of their height (3-, 6- and 9-storey) and include regular and irregular frames. Each structure frame was designed based on Eurocode 2 and 3 with the aid of Eurocode 8 for earthquake loading. The SAP2000 software was used as the main tool for the pushover analysis and incremental dynamic analysis. Readers are first provided with background information on the development of nonlinear analysis ...
There are no musts when it comes to outdoor activities. However, there is much that is good to know. Here I share with you attitudes, philosophy and sound advice that can help you shape an outdoor life that suits you.
This short book provides a concise study of the mechanics of head impact in a soccer heading manoeuvre. It describes the development and validation of finite element models of soccer ball and human head, as well as the simulation of brain dynamics after ball-to-head impact. In addition, it also presents a computational study of the efficacy of wearing protective headgear in mitigating the risk of concussion due to heading in soccer.
This short book describes the basic technological aspects involved in the creation of purely clinch and clinch-adhesive joints made of different types of adherent materials and employing different joining technologies. Basic parameters that need to be taken into account in the design process are also presented, while a comparison of experimental testing of the hybrid joint with simple clinching for a combination of different joining materials underlines the advantages of opting for hybrid joints. The book’s conclusions will facilitate the practical application of this new fastening technology.
This volume demonstrates the use of FORTRAN for numerical computing in the context of the finite element method. FORTRAN is still an important programming language for computational mechanics and all classical finite element codes are written in this language, some of them even offer an interface to link user-code to the main program. This feature is especially important for the development and investigation of new engineering structures or materials. Thus, this volume gives a simple introduction to programming of elasto-plastic material behavior, which is, for example, the prerequisite for implementing new constitutive laws into a commercial finite element program.
