Are you tired from many viewers one for each document?
Do you want to have, one program for all your technical documentations, scientific books and so on?
Do you want to have program, which fast opens files, fast loads pages and fast renders page to screen?
And all of this in free software?

Welding of Aluminium and Its Alloys by Gene Mathers

Welding of Aluminium and Its Alloys by Gene Mathers (Repost)
Publisher: CRC Press | 2002-10-16 | ISBN: 0849315514 | 236 pages | PDF | 3.64 MB
The Welding of Aluminium and its Alloys provides a basic understanding of the metallurgic principles underpinning how alloys achieve their strength and how welding can effect their properties. A practical guide for the shop-floor engineer, the book covers weldability of aluminium alloys, process description, advantages, limitations, proposed weld parameters, health and safety issues, preparation for welding, quality assurance and quality control issues, and problem solving. The book covers parent metal storage and preparation prior to welding, describes the more frequently encountered processes, and presents recommendations on welding parameters that may be used as a starting point for the development of a viable welding procedure.
Providing hints and tips that help you avoid some of the pitfalls of welding these sometimes problematic materials, the book's content is both descriptive and qualitative. The Welding of Aluminium and its Alloys is a concise and effective reference for engineers who may have little prior understanding of metallurgy and only a brief acquaintance with the welding processes involved.

Kindly have a look on the rough sketch of this municipal water supply pipe. The sump tank is 6 feet below ground level. I need to uplift the water to ground level ( so + 6 feet) by attaching another pipe to this municipal pipe. Of course without any pump. Is there any natural way? The pipe is on a natural slope of 2-3 deg which cannot be altered.
A NONLINEAR ANALYSIS METHOD FOR PERFORMANCE BASED SEISMIC DESIGN

Earthquake spectra vol.16
august 2000
peter fajfar,M.EERI
Abstract
A relatively simple nonlinear method for the seismic analysis of structures (the N2 method) is presented. It combines the pushover analysis of a multi-degree-of-freedom (MDOF) model with the response spectrum analysis of an equivalent single-degree-of-freedom (SDOF) system. The method is formulated in the acceleration-displacement format, which enables the visual interpretation of the procedure and of the relations between the basic quantities controlling the seismic response. Inelastic spectra, rather than elastic spectra with equivalent damping and period, are applied. This feature represents the major difference with respect to the capacity spectrum method. Moreover, demand quantities can be obtained without iteration. Generally, the results of the N2 method are reasonably accurate, provided that the structure oscillates predominantly in the first mode. Some additional limitations apply. In the paper, the method is described and discussed, and it basic derivations are given. The similarities and differences between the proposed method and the FEMA 273 and ATC 40 nonlinear static analysis procedures are discussed. Application of the method is illustrated by means of an example.

With very few books adequately addressing ASME Boiler & Pressure Vessel Code, and other international code issues, Pressure Vessels: Design and Practice provides a comprehensive, in-depth guide on everything engineers need to know.
With emphasis on the requirements of the ASME this consummate work examines the design of pressure vessel components with explanations that clearly emphasize the inherent design principles and philosophy. Chapters thoroughly cover stresses in shells, covers and flanges, vessel supports, and includes reviews of fatigue and fracture mechanics, structural stability, and limit analysis. With equations and procedures for designing the main parts of pressure vessels, this volume is a convenient resource and reference.
Pressure Vessels: Design and Practice covers the basic theories and principles behind the stress limiting conditions in the codes. It is also a practical guide for designing and building pressure vessels of all types. Not just a 'cookbook, ' this volume allows you to trace the origin of the design equations used in the construction codes, offering a valuable, physical insight into the design process.
