This book presents research on the Boundary Element Method in dynamics of continua. The main emphasis is on the development of the different boundary element formulations for time-dependent problems and the necessary mathematical transformations to produce computer codes that are able to solve scalar, elastic, and poroelastic wave propagation problems. A substantial part of the book also covers the application of the BEM to important engineering dynamic problems.

This book is written for engineering students and practicing engineers who have little knowledge of the boundary element method. Engineers and students have tended to be discouraged by complex mathematics usually employed in explaining this method, which has led to the popularity of the finite element method. This book attempts to redress the balance. It limits the mathematics to one chapter and breaks down the derivation of the formulation into logical steps, allowing the reader to focus on their particular applications. The book features coverage of all important boundary element applications, a step-by-step approach to the formulation and fully documented computer listing providing practical application solutions. It is aimed at research and development engineers and undergraduate and postgraduate students of applied mathematics, numerical computation and advanced mathematics in mechanical, civil and aeronautical departments.

This book deals with the safety assessment of structures and structural components, possibly operating beyond the elastic limits under variable repeated thermo-mechanical loads. Examples of such situations can be found both in mechanical and civil engineering (e.g. transportation technologies, pressure vessels, pipelines, offshore platforms, dams, pavements and buildings in seismic zones). So-called "direct” methods are focused, based on the shakedown theorems and their specialisation to limit theorems. These methods are receiving increased attention for the prediction of structural failure because they provide the information that is essential in practice (e.g. safety factor and collapse mechanisms) by more economical procedures than step-by-step inelastic analysis; also, they only need a minimum of information on the evolution of loads as functions of time. The addressed audience are primarily engineers and scientists active in Structural Engineering and Safety and Reliability Analysis.

Shakedown of Elastic-Plastic Structures - 1st Edition
Author(s)/Editor(s): J.A. König | Size: 4 MB | Format:PDF | Quality:Scanner | Publisher: North Holland | Year: 1987 | pages: 219 | ISBN: 9780080983844
In this book, the author has collected existing information on the analysis of elastic-plastic structures subjected to variable repeated loads and to variable temperature fields. He presents the foundations of the theory and its applications to the shakedown analysis of structures of various types and to computational algorithms.
The book provides useful and interesting material for students of civil and mechanical engineering, practising engineers with a good mathematical background and also scientists concerned with the analysis of inelastic structures.

Lynda.com - Construction Management Planning and Scheduling
Publisher: Lynda.com
Peresented By: Jim Rogers
Format: mp4
Duration: 01:25
Size: 926 MB
Quality: DVDRip
Schedules are management tools that allow leaders to make informed decisions about activities on a construction site. Although the terms planning and scheduling are often used interchangeably, there is a significant difference between these two activities, and an accurate schedule cannot be developed without first developing a proper plan. Planning activities involve developing the logic of how a project is to be constructed—beginning with the construction documents that define the end product, and then identifying the individual tasks or steps required to arrive at this end result. Scheduling consists of integrating the plan with a calendar or time period, and assigning time durations and resources to each task.
This course identifies the steps needed to develop a proper plan, and demonstrates how that plan is transformed into a construction schedule. Throughout the course, instructor Jim Rogers shares examples of his own successes and failures in the areas of construction planning and scheduling, so as to lend real-world context to the concepts he covers.
Topics include:
-Types of schedules
-Planning versus scheduling
-Work breakdown structure
-Developing a schedule
-Creating a network model
-Assigning durations, costs, and resources
-Identifying the critical path
-Letting the software do the calculations
-Checking and updating the schedule
-Scheduling's impact on productivity

Methods of structural control and dynamics are introduced in this book. These include reduction of large structural models by balanced truncation, placement of actuators and sensors for dynamic testing and control, structural identification of the minimum-order balanced representation, balanced dissipative controller design, balanced LQG and H( controller designs with the closed-form relationships between controller parameters and system performance, and controller reduction methods that preserve the closed-loop performance. The book explores the unique properties of flexible structures to obtain efficient methods of dynamic analysis and controller design. The presented methods of structural dynamics, identification, sensor/actuator placement, and passive, LQG and H( controller design have been checked both with simulations and industrial implementations.
