Numerical Solution of Partial Differential Equations in Science and Engineering
Author: Leon Lapidus, George F. Pinder | Size: 11.9 MB | Format:PDF | Publisher: Wiley | Year: 1999 | pages: 677 | ISBN: 9780471359449
Incorporates the essential elements of all the numerical methods currently used in the solution of partial differential equations encountered in science and engineering. Considers partial differential equations by their type (parabolic, elliptic, or hyperbolic), and applies all relevant numerical schemes to each type. All material included is presented free of specialized notation and terminology.
From the reviews of Numerical Solution of Partial Differential Equations in Science and Engineering:
* "The book by Lapidus and Pinder is a very comprehensive, even exhaustive, survey of the subject . . . [It] is unique in that it covers equally finite difference and finite element methods."-Burrelle's.
* "The authors have selected an elementary (but not simplistic) mode of presentation. Many different computational schemes are described in great detail . . . Numerous practical examples and applications are described from beginning to the end, often with calculated results given."-Mathematics of Computing.
* "This volume . . . devotes its considerable number of pages to lucid developments of the methods [for solving partial differential equations] . . . the writing is very polished and I found it a pleasure to read!"-Mathematics of Computation
Contents:
Fundamental Concepts.
Basic Concepts in the Finite Difference and Finite Element Methods.
Finite Elements on Irregular Subspaces.

Description
The objective of this book is to provide engineers with the necessary tools and techniques for formulating plans, designs, cost estimates and specifications for pipeline construction and field maintenance and modernization programs. Packed with easy to read and understand tables, pipeline schematics, bullet lists and "what to do next" checklists. This easy to use book covers the design, construction, and operation of onshore pipeline systems. The incorporate construction methods, commissioning, pressure testing, and start up into the design of a pipeline system. The focus is on pipeline routing, mechanical design, construction methods, hydraulics, installation, and operations of onshore pipeline systems. With this book readers will acquire and/or consolidate the essential knowledge and skills to design, construct, and operate pipelines. Design and simulation problems are an integral part of this book. With this book in hand, engineers will be able to:
Routine auditing of technical work output relative to technical input and established criteria and expectations.
Assessment and estimation of work scope including pipeline design integrity and resourcing requirements from enquiry through to project completion.
To carry out conceptual designs in support of concept selection studies.

Analysis of Cracks in Solids: Advances in Fracture Mechanics
The need for progress in modelling and analysis of crack problems in solids has resulted in renewed attempts at using modern approaches to boundary value problems. By taking a different viewpoint on the traditional treatment of many problems, such as crack theory, the range that can be resolved through mathematical tools is enlarged. This book provides a fresh outlook on crack problems, displaying new methods of studying these and proposing new models for cracks in elastic and nonelastic bodies satisfying physically suitable nonpenetration conditions between crack faces. Two- and three-dimensional bodies, plates and shells with cracks are considered. Properties of solutions such as existence of solutions, regularity up to the crack faces, and convergence of solutions as parameters of a system are varying are established, while different constitutive laws such as elastic, thermoelastic and elastoplastic are also analysed. The new approach presented by the authors is intriguing because it fails to lead to violation of physical properties. In addition, the boundary conditions analysed are given in the form of inequalities, and are properly nonpenetration conditions of crack faces. This implies that similar problems may be considered from the contact mechanics standpoint. The contents are divided under the following headings: Introduction; Cracks in Plates and Shells; Cracks in Complicated Plates; Variation of Cracks in Solids; and Cracks in Elastoplastic Bodies.

In 1971 the Institution of Structural Engineers published a report on the Stability of modern buildings as a result of its conference on industrialized buildings, the collapse of prefabricated buildings under erection at Aldershot and the aftermath of the tragic accident at Ronan Point. That report was largely concerned with high-rise construction, and it was in 1984 that the Institution formed a Committee to prepare a successor to deal
with stability of all types of building whether high or low rise.
The new report was to describe the disturbing forces, to advise on stability for most forms of construction, and to consider stability during construction.
One ofthe difficulties facing the Committee was to arrive at a definition of stability for buildings and how to separate considerations of stability from those of strength. Expressions such as 'sensitivity', 'structural integrity', 'robustness' and 'lack of obviousor hidden wobbliness' were put before the Committee but rejected in favour of 'stability' with a definition in the text.
The report sets out the many aspects of design and construction that have to be taken into account so that structures remain in a stable state at all times. It is hoped that it will make a positive contribution to good practice in the office and on site.
