Experimental solid mechanics is the study of materials to determine their physical properties. This study might include performing a stress analysis or measuring the extent of displacement, shape, strain and stress which a material suffers under controlled conditions. In the last few years there have been remarkable developments in experimental techniques that measure shape, displacement and strains and these sorts of experiments are increasingly conducted using computational techniques. Experimental Mechanics of Solids is a comprehensive introduction to the topics, technologies and methods of experimental mechanics of solids. It begins by establishing the fundamentals of continuum mechanics, explaining key areas such as the equations used, stresses and strains, and two and three dimensional problems. Having laid down the foundations of the topic, the book then moves on to look at specific techniques and technologies with emphasis on the most recent developments such as optics and image processing. Most of the current computational methods, as well as practical ones, are included to ensure that the book provides information essential to the reader in practical or research applications. Key features: Presents widely used and accepted methodologies that are based on research and development work of the lead author Systematically works through the topics and theories of experimental mechanics including detailed treatments of the Moire, Speckle and holographic optical methods Includes illustrations and diagrams to illuminate the topic clearly for the reader Provides a comprehensive introduction to the topic, and also acts as a quick reference guide This comprehensive book forms an invaluable resource for graduate students and is also a point of reference for researchers and practitioners in structural and materials engineering.
This guidebook demonstrates how a state transportation agency (STA) can improve its project scoping process (PSP) and practices to produce a project cost estimate and schedule that facilitate programming decision making and accountability. It illustrates the effort needed to develop a robust cost estimate and then manage to a baseline budget and scope throughout the project delivery cycle. The guidebook consists of two parts. Part 1, “Research Results about the PSP,” addresses the following issues: why STAs should formalize the PSP; current practices for PSP; and how agencies can implement an effective PSP. Part 2, “Implementation Guidelines,” provides an easy-to-understand layout and describes how to implement the PSP. The guidelines are divided into three sections. Each section details one of the three major activities of the PSP—develop the project, analyze the alternatives and document findings, and develop the recommended alternative. The guidelines also have two appendices. The first appendix summarizes the tools that can be used while performing different activities in the scope development process. The second appendix is the list of online links to various resources and tools to support the PSP, as referenced in this guidebook.
A shocking tale of tragedy and confusion as a normal student finds her girlfriend murdered on a school room only to see her alive and well the next day, which starts a downwards spiral of paranoia and delusions that goes unresolved until the tale's climax.
