This book discusses free vibration of single-degree-of-freedom (SDOF) systems and forced vibration of SDOF systems. It covers response to periodic dynamic loadings and impulse loads and two degrees of freedom linear system response methods and free vibration of multiple degrees of freedom. Topics include time history response by natural mode superposition, numerical solution methods for natural frequencies and mode shapes and differential quadrature, transformation, and Finite Element methods for vibration problems. The book also touches on earthquake ground motion, response spectra, and earthquake analysis of linear systems are discussed. Worked examples in Mathematica and Matlab are given.

The repair of deteriorated, damaged and substandard civil infrastructures has become one of the most important issues for the civil engineer worldwide. This book discusses the use of externally bonded fibre-reinforced polymer (FRP) composites to strengthen, rehabilitate and retrofit civil engineering structures, covering such aspects as material behavior, structural design and quality assurance.
The first three chapters of the book review structurally deficient civil engineering infrastructure, including concrete, metallic, masonry, and timber structures. FRP composites used in rehabilitation and surface preparation of the component materials are also reviewed. The next four chapters deal with the design of FRP systems for the flexural and shear strengthening of reinforced concrete (RC) beams and the strengthening of RC columns. The following two chapters examine the strengthening of metallic and masonry structures with FRP composites. The last four chapters of the book are devoted to practical considerations in the flexural strengthening of beams with unstressed and prestressed FRP plates, durability of externally bonded FRP composite systems, quality assurance and control, maintenance, repair, and case studies.
With its distinguished editors and international team of contributors, Strengthening and rehabilitation of civil infrastructures using fibre-reinforced polymer (FRP) composites will be a valuable reference guide for engineers, scientists and technical personnel in civil and structural engineering working on the rehabilitation and strengthening of the civil infrastructure.

Applied Metal Forming: Including FEM Analysis >> By Henry S. Valberg (Author)
Author: Henry S. Valberg | Size: 13.1 MB | Format:PDF | Publisher: Cambridge University Press; 1 edition | Year: 31 Mar 2010 | pages: 477 | ISBN: ISBN-10: 0521518237 ISBN-13: 978-0521518239
Product Description Applied Metal Forming: Including FEM Analysis describes metal forming theory and how experimental techniques can be used to study any metal forming operation with great accuracy. For each primary class of processes, such as forging, rolling, extrusion, wiredrawing, and sheet-metal forming, it explains how FEA (Finite Element Analysis) can be applied with great precision to characterize the forming condition and in this way optimize the processes. FEA has made it possible to build very realistic FEM-models of any metal forming process, including complex three-dimensional forming operations, in which complex products are shaped by complex dies. Thus, using FEA it is now possible to visualize any metal forming process and to study strain, stresses, and other forming conditions inside the parts being manufactured as they develop throughout the process.
Book Description
This book outlines metal forming theory and how experimental methods are utilized to understand how metal forming works. For each main process, such as forging, rolling, extrusion, wiredrawing, and sheet-metal forming, it demonstrates how FEA (Finite Element Analysis) can accurately characterize the forming condition and therefore optimize the processes.
