BOOK EXCERPT:
We are all familiar with impact. Lesser impacts such as hammering a nail, cracking an egg or stubbing a toe are part of everyday life. More violent impacts such as those caused by car crashes or bullets are fortunately less common but are still well enough known to be taken for granted. Very violent impacts such as meteorites striking the earth are outside our personal experience but we are aware of them. Despite this, impacts remain mysterious. They occur too quickly for us to follow what is happening and the evidence they leave behind is often ambiguous. Over the last thirty years improvements in high speed instrumen tation and developments in computing have made them more comprehensible and an increasing amount of attention is being paid to the subject which is an area of expanding scientific and engineering research. A multi-disciplinary approach is not yet established and information is scattered in many places and expressed in a variety of jargons. In applied mathematics, impacts have provided interesting theoretical problems with elegant solutions but it has been difficult to check results experimentally. Impacts can change the behaviour of materials but similar changes can sometimes be produced in other ways and the underlying mechanisms are not clear. Empirical solutions to engineering problems have worked reasonably well but it is hard to know what to do if things go wrong.

BOOK EXCERPT:
This second edition of Impact Engineering covers the dynamic analysis of structures undergoing small to large displacements, linear and nonlinear elastic material behavior to viscoplasticity, and the range of features of structural impact analysis. Individuals, as well as various governing bodies are concerned about protection against natural hazards, crash-type accidents, and terrorism- commonly referred to as "impact"- implying a rapid loading process. The book discusses the physics involved in such impact situations and incorporates analytical considerations as well as techniques to obtain and interpret experimental data and relevant numerical techniques. It also includes a chapter on scaling which is a relevant aspect when studying impact on large structures. This book will be useful for advanced students and professionals in civil and mechanical engineering as well as for students and researchers in applied physics and other relevant disciplines.

BOOK EXCERPT:
This book is intended to help the reader understand impact phenomena as a focused application of diverse topics such as rigid body dynamics, structural dynamics, contact and continuum mechanics, shock and vibration, wave propagation and material modelling. It emphasizes the need for a proper assessment of sophisticated experimental/computational tools promoted widely in contemporary design. A unique feature of the book is its presentation of several examples and exercises to aid further understanding of the physics and mathematics of impact process from first principles, in a way that is simple to follow.

BOOK EXCERPT:
This unique compendium presents the Gradient Smoothing Methods (GSMs), as a general solver for linear and nonlinear PDEs (Partial Differential Equations) with a focus on fluids and flowing solids.The volume introduces the basic concepts and theories of the gradient smoothing technique used in the GSMs. Formulations for both Eulerian-GSM and Lagrangian-GSM are presented. The key ingredients of GSMs and its effectiveness in solving challenging fluid/solid flow problems with complex geometries are then discussed.Applications of GSM are highlighted, including compressible and incompressible flows, hydrodynamics with flexible free surface, and flowing solids with material strength and large deformation in geotechnical engineering, in particular, landslide simulations.In-house MATLAB codes are provided for both Eulerian and Lagrangian GSMs, along with detailed descriptions. More efficient FORTRAN source codes for solving complex engineering problems are also available on Github.
