In this book Emphasis was placed on the practical application of fracture mechanics, but it was aimed to treat the subject in a way that may interest both metallurgists and engineers. A general discussion is provided on fracture mechanisms, fracture criteria and other metallurgical aspects, without going into much detail. Numerous references are provided to enable a more detailed study of these subjects which are still in a stage of speculative treatment. Metallurgists and mechanicists need to know the particular problems of industry in order to be able to respond to the demands of engineers. Therefore some pertinent practical problems are discussed.

Optimization Concepts and Applications in Engineering
Author: Ashok D. Belegundu, Tirupathi R. Chandrupatla | Size: 2.4 MB | Format:PDF | Publisher: Cambridge University Press | Year: 2011 | pages: 479 | ISBN: 9780521878463
It is vitally important to meet or exceed previous quality and reliability standards while at the same time reducing resource consumption. This textbook addresses this critical imperative integrating theory, modeling, the development of numerical methods, and problem solving, thus preparing the student to apply optimization to real-world problems. This text covers a broad variety of optimization problems using: unconstrained, constrained, gradient, and non-gradient techniques; duality concepts; multiobjective optimization; linear, integer, geometric, and dynamic programming with applications; and finite element-based optimization. In this revised and enhanced second edition of Optimization Concepts and Applications in Engineering, the already robust pedagogy has been enhanced with more detailed explanations, an increased number of solved examples and end-of-chapter problems. The source codes are now available free on multiple platforms. It is ideal for advanced undergraduate or graduate courses and for practicing engineers in all engineering disciplines, as well as in applied mathematics

Pervious concrete pavement is a unique and effective means to meet growing environmental demands. By capturing rainwater and allowing it to seep into the ground, pervious concrete is instrumental in recharging groundwater, reducing stormwater runoff, and meeting U.S. Environmental Protection Agency (EPA) stormwater regulations. In fact, the use of pervious concrete is among the Best Management Practices (BMP) recommended by the EPA— and by other agencies and geotechnical engineers across the country—for the management of stormwater runoff on a regional and local basis. This pavement technology creates more efficient land use by eliminating the need for retention ponds, swales, and other stormwater management devices. In doing so, pervious concrete has the ability to lower overall project costs on a first-cost basis. In pervious concrete, carefully controlled amounts of water and cementitious materials are used to create a paste that forms a thick coating around aggregate particles. A pervious concrete mixture contains little or no sand, creating a substantial void content. Using sufficient paste to coat and bind the aggregate particles together creates a system of highly permeable, interconnected voids that drains quickly. Typically, between 15% and 25% voids are achieved in the hardened concrete, and flow rates for water through pervious concrete typically are around 480 in./hr (0.34 cm/s, which is 5 gal/ft2/ min or 200 L /m2/min), although they can be much higher. Both the low mortar content and high porosity also reduce strength compared to conventional concrete mixtures, but sufficient strength for many applications is readily achieved. While pervious concrete can be used for a surprising number of applications, its primary use is in pavement. This report will focus on the pavement applications of the material, which also has been referred to as porous concrete, permeable concrete, no-fines concrete, gap-graded concrete, and enhanced-porosity concrete.

Temporary Structures-Horizontal Formwork Design and Formwork Design Tables
Author: Professor Kamran M. Nemati | Size: 632 KB | Format:PDF | Publisher: UNIVERSITY OF WASHINGTON, DEPARTMENT OF CONSTRUCTION MANAGEMENT | Year: 2007 | pages: 17
This lesson provides an overview on the basic structural wood design as it applies to concrete formwork. This lesson covers materials, methods and techniques associated with concrete formwork design and construction for slabs. This lesson intends to provide enough information to be able to design horizontal forms, which will be covered in step-by-step fashion in lesson 2. Also in this lesson, the use of design tables will be discusses. The design tables are used for preliminary design when rigorous structural analysis is required for formwork design.
