Product Description
This research report contains results obtained by the authors in recent years in the research area of dynamic fracture mechanics and wave propagation in damaged solids. It deals with several topics on wave propagation in elastic solids with cracks.

Coverage includes wave scattering problems by a single crack, a periodic array of collinear cracks in isotropic and transversely isotropic elastic solids, interface cracks with a periodic spacing, and randomly distributed micro-cracks.

The authors present a non-hypersingular boundary integral equation method to treat single-crack wave scattering problems, both in time- and frequency-domain. Numerical examples are given to show the accuracy and efficiency of the method. ... Read more

Product Description
Predicting Motion presents the core ideas of Newtonian mechanics, starting from Newton's laws and the idea that changes in motion are predictable given the forces that cause them. Richly illustrated with questions and answers for self-assessment, it carefully introduces concepts, such as kinetics and potential energy, linear momentum, torque (the rotational analogue of force), and angular momentum, and explains their role in predicting motion. Although no prior knowledge of this topic is required, the book focuses on the significance of differential equations in making such predictions. It also provides an up-to-date treatment of mechanics with accounts of relativistic collisions and the implications of chaos theory for the future of the solar system and for galaxies that contain black holes. ...

Product Description

This book presents a detailed and rigorous account of the work of Tobias Mayer, a mathematician and astronomer of the middle 18th century. Mayer's most famous contribution is his set of lunar tables, which were the best available in their time. The use of lunar tables was the most sophisticated method to calculate latitude. Because of their accuracy, Mayer's lunar tables became very popular and were used extensively in nautical navigation.

The book focuses on three of Mayer's major achievements:

-First, is Mayer's dynamical lunar theory based on Newton's principle of gravitation. His theory is compared to Euler's work in celestial mechanics of the same period. Evidence is presented that refutes the commonly held opinion that Mayer's lunar theory was just a variant of Euler's, although certain similarities between the theories do exist.

-Second, the special computational scheme that is embodied in Mayer's lunar tables is investigated. This scheme is shown to originate in Newton's lunar theory of 1702.

-Lastly, the book provides a detailed analysis of Mayer's process of adjusting the coefficients of his lunar tables to fit an extensive collection of observational data. This regression technique can be considered a precursor to the later formalized least squares method.

This book is the most complete and accurate account of Tobias Mayer's contributions to lunar theory.

Product Description

Isaac Newton developed three laws of motion that govern the everyday world. These laws are usually presented in purely mathematical forms, but Jason Zimba breaks with tradition and treats them visually. This unique approach allows students to appreciate the conceptual underpinnings of each law before moving on to qualitative descriptions of motion and, finally, to the equations and their solutions.

Zimba has organized the book into seventeen brief and well-sequenced lessons, which focus on simple, manageable topics and delve into areas that often cause students to stumble. Each lesson is followed by a set of original problems that have been student-tested and refined over twenty years.

Zimba illustrates the laws with more than 350 diagrams, an innovative presentation that offers a fresh way to teach the fundamentals in introductory physics, mechanics, and kinematics courses.

Product Description

The short series The Historical Epistemology of Mechanics presents the long-term development of mechanical knowledge. The books in this series combine the presentation of a broad selection of relevant sources with in-depth analyses of the long-term development of mechanical knowledge focusing on the early modern period. This series is conceived in analogy to the four-volume series on The Genesis of General Relativity (BSPS 250).

The English Galileo, the first book in this series, investigates the shared knowledge of preclassical mechanics by relating the work of Thomas Harriot on motion, documented by a wealth of manuscripts, to that of Galileo and other contemporaries.

Harriot and Galileo indeed exploited the same shared knowledge resources in order to approach the same challenging objects. While the paths Harriot traces through the shared knowledge are different from Galileo’s, the work of the two scientists displays striking similarities as regards their achievements as well as the problems they were unable to solve. The study of Harriot’s parallel work thus allows the exploration of the structure of the shared knowledge of early modern mechanics, to perceive possible alternative histories, and to distinguish between individual peculiarities and shared structures of early modern mechanical reasoning. This study has received two distinguished awards, the Junior Scholar Award of the Georg Agricola Society and the Georg Uschmann Award of the German National Academy of Sciences, Leopoldina.

For Kindergarten Students, Maybe
I purchased this book thinking it would explain the physics behind Roller Coasters.It does in the most general and vague terms.If you're looking for formulae and data, forget it.A kindergarten student could follow it easy enough.Definitely ripped off for what I paid.Sorry, but that's the way I feel.Should be an $8.00 book in softcover, saddle stitched. ...

Product Description

This book describes several tractable theories for fluid flow in porous media. The important mathematical quations about structural stability and spatial decay are address. Thermal convection and stability of other flows in porous media are covered. A chapter is devoted to the problem of stability of flow in a fluid overlying a porous layer.

Nonlinear wave motion in porous media is analysed. In particular, waves in an elastic body with voids are investigated while acoustic waves in porous media are also analysed in some detail.

A chapter is enclosed on efficient numerical methods for solving eigenvalue problems which occur in stability problems for flows in porous media.

Brian Straughan is a professor at the Department of Mathemactical Sciences at Durham University, United Kingdom.

Product Description

This volume introduces and reviews novel theoretical approaches to modeling strongly nonlinear behaviour of either individual or interacting structural mechanical units such as beams, plates and shells or composite systems thereof.

The approach draws upon the well-established fields of bifurcation theory and chaos and emphasizes the notion of control and stability of objects and systems the evolution of which is governed by nonlinear ordinary and partial differential equations. Computational methods, in particular the Bubnov-Galerkin method, are thus described in detail.

Product Description
High Quality Content by WIKIPEDIA articles! This article describes a particle in planar motion when observed from non-inertial reference frames. The most famous examples of planar motion are related to the motion of two spheres that are gravitationally attracted to one another, and the generalization of this problem to planetary motion. See centrifugal force, two-body problem, orbit and Kepler's laws of planetary motion. Those problems fall in the general field of analytical dynamics, the determination of orbits from given laws of force. This article is focused more on the kinematical issues surrounding planar motion, that is, determination of the forces necessary to result in a certain trajectory given the particle trajectory. General results presented in fictitious forces here are applied to observations of a moving particle as seen from several specific non-inertial frames, for example, a local frame (one tied to the moving particle so it appears stationary), and a co-rotating frame (one with an arbitrarily located but fixed axis and a rate of rotation that makes the particle appear to have only radial motion and zero azimuthal motion). The Lagrangian approach to fictitious forces is introduced. ... Read more
