The capability to predict the nonlinear response of beams, plates and shells when subjected to thermal and mechanical loads is of prime interest to structural analysis. In fact, many structures are subjected to high load levels that may result in nonlinear load-deflection relationships due to large deformations. One of the important problems deserving special attention is the study of their nonlinear response to large deflection, postbuckling and nonlinear vibration.
A two-step perturbation method is firstly proposed by Shen and Zhang (1988) for postbuckling analysis of isotropic plates. This approach gives parametrical analytical expressions of the variables in the postbuckling range and has been generalized to other plate postbuckling situations. This approach is then successfully used in solving many nonlinear bending, postbuckling, and nonlinear vibration problems of composite laminated plates and shells, in particular for some difficult tasks, for example, shear deformable plates with four free edges resting on elastic foundations, contact postbuckling of laminated plates and shells, nonlinear vibration of anisotropic cylindrical shells. This approach may be found its more extensive applications in nonlinear analysis of nano-scale structures.
Concentrates on three types of nonlinear analyses: vibration, bending and postbuckling
Presents not only the theoretical aspect of the techniques, but also engineering applications of the method
A Two-Step Perturbation Method in Nonlinear Analysis of Beams, Plates and Shells is an original and unique technique devoted entirely to solve geometrically nonlinear problems of beams, plates and shells. It is ideal for academics, researchers and postgraduates in mechanical engineering, civil engineering and aeronautical engineering.

WinRAR is a powerful archive manager. RAR files can usually compress content by 8 percent to 15 percent more than ZIP files can. WinRAR is a powerful compression tool with many integrated additional functions to help you organize your compressed archives. It can backup your data and reduce size of email attachments, decompress RAR, ZIP and other files downloaded from Internet and create new archives in RAR and ZIP file format.
WinRAR puts you ahead of the crowd when it comes to compression. By consistently creating smaller archives, WinRAR is often faster than the competition. This will save you disc space, transmission costs AND valuable working time as well. WinRAR is ideal for multimedia files. WinRAR automatically recognizes and selects the best compression method. The special compression algorithm compresses multimedia files, executables and object libraries
Features of WinRAR:
- Using WinRAR puts you ahead of the crowd when it comes to compression by consistently making smaller archives than the competition, saving disk space and transmission costs.
- WinRAR provides complete support for RAR and ZIP archives and is able to unpack CAB, ARJ, LZH, TAR, GZ, ACE, UUE, BZ2, JAR, ISO, 7Z, Z archives.
- WinRAR offers a graphic interactive interface utilizing mouse and menus as well as the command line interface.
- WinRAR is easier to use than many other archivers with the inclusion of a special "Wizard" mode which allows instant access to the basic archiving functions through a simple question and answer procedure. This avoids confusion in the early stages of use.
- WinRAR offers you the benefit of industry strength archive encryption using AES (Advanced Encryption Standard) with a key of 128 bits.
- WinRAR supports files and archives up to 8,589 billion gigabytes in size. The number of archived files is, for all practical purposes, unlimited.
- WinRAR offers the ability to create selfextracting and multivolume archives.
Recovery record and recovery volumes allow to reconstruct even physically damaged archives.
- WinRAR features are constantly being developed to keep WinRAR ahead of the pack.

Handbook of Tunnel Engineering I: Structures and Methods
Author: Bernhard Maidl, Markus Thewes, Ulrich Maidl | Translator: David S. Sturge | Size: 24 MB | Format:PDF | Quality:Original preprint | Publisher: Ernst & Sohn | Year: 2013 | Pages: 455 | ISBN: 9783433030486, 9783433603505, 9783433603512, 9783433603529, Â 9783433603499
Tunnel engineering is one of the oldest, most interesting but also challenging engineering disciplines and demands not only theoretical knowledge but also practical experience in geology, geomechanics, structural design, concrete construction, machine technology, construction process technology and construction management. The two-volume "Handbuch des Tunnel- und Stollenbaus" has been the standard reference for German-speaking tunnellers in theory and practice for 30 years. The new English edition is based on a revised and adapted version of the third German edition and reflects the latest state of knowledge. The book is published in two volumes, with the first being devoted to more practical themes of construction and construction process in drill and blast and mechanised tunnelling. Microtunnelling and ventilation are also dealt with. All chapters include practical examples.
