This book investigates the factors that lead to slip and fall incidents and establishes a relationship between the coefficient of friction (COF), floor slipperiness and floor roughness. It also examines human perception of slipperiness through measured coefficient of friction (COF). On the basis of questionnaire surveys among manufacturing workers, it identifies potential risk factors and assesses human perceptions of slipperiness. It also uses a tribology approach to relate the interaction between contaminants, floor and footwear materials.
This book focuses on the analysis and treatment of osteoporotic bone based on drug administration, tracking fatigue behavior and taking into consideration the mechanical interaction of implants with trabecular bone. Weak trabeculae are one of the most important clinical features that need to be addressed in order to prevent hip joint fractures.
This book develops and analyses computational wear simulations of the total ankle replacement for the stance phase of gait cycle. The emphasis is put on the relevant design parameters. The book presents a model consisting of three components; tibial, bearing and talar representing their physiological functions.
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 ebook is a compilation of papers presented at the Malaysian International Tribology Conference 2015 (MITC2015) - Penang, Malaysia on 16 ~ 17 November 2015.
This book provides comprehensive mechanobiological insights into bone, including the microstructure of cancellous bone and its realistic loading in the human body. This approach considers different types of loads, i.e. static and dynamic, and the response under uniaxial and multiaxial loading conditions. The book also reviews additional factors influencing biomechanical properties, e.g. fluid transport. In closing, the mechanobiological approach is discussed in the context of the finite element method.
This book introduces engineering principles into the sport of rowing by the integration of rower biomechanics, stroke style, and blade hydrodynamics to improve the rowing performance in the sport. The book starts with an essential overview of rowing, covering its history, governing organizations, and the stroke phases. It looks into the biomechanical and hydrodynamic aspects, emphasizing different body segments and stroke styles contributing to rower performance. Key performance parameters are discussed, such as peak force, stroke rate, and hydrodynamic force. It also highlights the utilization of dynamic rowing simulators and specialized sensors to collect crucial performance assessment and improvement data. By addressing the engineering aspects of the sport, the book offers the potential for performance enhancement, ultimately benefiting the rowing community and advancing sports science.
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 book presents a set of experimental studies and numerical simulation of cancellous bone material, the goal being to promote the development of artificial cancellous bones. In the development context, two major factors need to be considered: the integrity of the overall structure and its permeability. The challenge is to mimic and develop synthetic cancellous bone to offer performance that is comparable to natural cancellous bone structures, especially for load-bearing applications.
This short monograph presents an analysis and design methodology for shape memory alloy (SMA) components such as wires, beams, and springs for different applications. The solid-solid, diffusionless phase transformations in thermally responsive SMA allows them to demonstrate unique characteristics like superelasticity and shape memory effects. The combined sensing and actuating capabilities of such materials allows them to provide a system level response by combining multiple functions in a single material system. In SMA, the combined mechanical and thermal loading effects influence the functionality of such materials. The aim of this book is to make the analysis of these materials accessible to designers by developing a "strength of materials" approach to the analysis and design of such SMA components inspired from their various applications with a review of various factors influencing the design process for such materials.
