Autodesk InfraWorks is a conceptual modeling tool that helps civil engineers to create and demonstrate the proposals. The program allows you to quickly create visual conceptual models, inscribed into the environment. Designers can easily evaluate different design options. The rich design tools allow us to demonstrate the success of project proposals to interested parties.

we are really sorry and apologize for recent issue on site, due to terminating our server panel due to US embargo, and also doing some improvement on server, we prepare new server with new HTTP webserver and accelerator on it. We worked more than 10 days for preparing it. we tested it before switching on new server and all things looks good, then we switched DNS records to new server, new DNS usually need 24-72 hours to apply to all internet provider in the world, unfortunately after this work done we found due to a issue users can not log-n forum also we do not have any access to admin control panel, we (support team) start works on new server to fix the issue and we decided to change DNS record to old server again to bring p forum again, unfortunately this changes need 24-72 hours again to be applied.
All these works is for having best place for large amount of users. Security, Performance are going to increase.
any way we apologize you for this issue. and we`ll announce that may be some like issue will be happen till fully migration to new server done.

This volume emphasizes fundamental concepts, both on the development of mathematical models of fracture phenomena and on the analysis of these models. Cases involving stress waves impinging on cracks, tractions suddenly applied to the faces of cracks, and rapid crack growth and arrest are considered in detail. Most of the work is concerned with the behavior of nominally elastic materials, but available results on elastic-plastic and elastic-viscoplastic materials are included. Connections to experimental results and to applications in structural mechanics, seismology, and materials science are noted whenever possible.

Covering a wide variety of topics in dynamic fracture mechanics, this volume presents state-of-the-art experimental techniques and theoretical analysis on dynamic fracture in standard and exotic materials. Written by world renowned researchers, this valuable compendium contains eleven chapters on crack initiation, crack propagation, crack arrest, crack-stress wave interactions, and experimental, analytical and numerical methods in dynamic fracture mechanics.

Dynamics With Friction: Modelling, Analysis and Experiment
Author: Ardeshir Guran, Friedrich Pfeiffer, Karl Popp | Size: 12.7 MB | Format:PDF | Quality:Unspecified | Publisher: World Scientific Pub Co Inc | Year: 2001 | pages: 329 | ISBN: 9789810229542
The dynamics of dissipative mechanical and structural systems is being investigated at various institutions and laboratories worldwide with ever-increasing sophistication of modelling, analysis and experiments. This book offers a collection of contributions from these research centres that represent the state-of-the-art in the study of friction oscillators. It provides the reader with the fruits of a team effort by leaders in this fascinating field. The present part 2 of this volume on dynamics with friction is a continuation of the previous part 1, and is designed to help synthesize our current knowledge regarding the role of friction in mechanical and structural systems as well as everyday life. The topics covered include interaction of vibration and friction at dry sliding contacts, friction-induced instability in disks, dynamics of lubricated flexible links in kinematic chains, modal interactions in periodic structures, dynamics of an experimentally excited beam, transient waves in viscoelastic materials, dynamic stability of plates with damping, friction modelling and dynamic computation, damping through use of passive and semi-active dry friction forces. This book gives a comprehensive picture of dynamics of dissipative mechanical and structural systems. It also gives an up-to-date account of the present state of the field. It should be of interest to engineers, rheologists, material scientists, applied mathematicians, physicists and historians of science and technology.
