Updated edition of a best-selling title – Author brings 25 years experience to the work – Addresses the key issues of economy and environment Marine pipelines for the transportation of oil and gas have become a safe and reliable way to exploit the valuable resources below the world?s seas and oceans. The design of these pipelines is a relatively new technology and continues to evolve in its quest to reduce costs and minimise the effect on the environment. With over 25years experience, Professor Yong Bai has been able to assimilate the essence of the applied mechanics aspects of offshore pipeline system design in a form of value to students and designers alike. It represents an excellent source of up to date practices and knowledge to help equip those who wish to be part of the exciting future of this industry.

This is something I have known since my hostel days at IIT Delhi in the seventies. I have wondered many times, and this could be a research topic.
If you take two eggs one in each hand, and then hit them one against the other, only one will break. That is how I break eggs, and for the last one left I have to hit it against the plate or fork ot whatever. When you hit the two eggs together, I never had to worry about small shell fragments. Try it yourself. Never once in the last 30 plus years have I broken them simultaneously.
Let us say Egg 1 (E1) and E2
You break E2. Then hit E1 and E3. Either E1 or E3 will break, and so forth.
Try it. Never fails. I have done it thousands of time.
My academic challenge to the forum - what is the mathematics/physics/material science behind this ? Please free to share with non CEA members. Someone can probably get a PhD for this, I hope.
i guess i dont need to explain what is the book about

General
HEC-6 (HEC, 1991) is a one-dimensional movable boundary open channel flow and sediment
model designed to simulate changes in river profiles due to scour and deposition over fairly long time
periods (typically years, although applications to single flood events are possible). The continuous flow
record is broken into a sequence of steady flows of variable discharge and duration. For each flow a
water surface profile is calculated thereby providing energy slope, velocity, depth, etc. at each cross
section. Potential sediment transport rates are then computed at each section. These rates, combined
with the duration of the flow allow for a volumetric accounting of sediment for each reach. The amount of
scour or deposition at each section is then computed and the cross section shape adjusted accordingly.
The computations then proceed to the next flow in the sequence and the cycle is repeated beginning with
the updated geometry. The sediment calculations are performed by grain size fraction thereby allowing for
the simulation of hydraulic sorting and armoring. Features of the model include: capability to analyze
networks of streams, automatic channel dredging, various levee and encroachment options, and several
options for computation of sediment transport rates.
Experience has shown that successful application of movable boundary models may require
substantial effort to reproduce field observations, i.e. calibration. This document complements the HEC-6
User's Manual (HEC, 1991) and provides guidelines for calibration and application. The general topic of
application and calibration of numerical river models is thoroughly covered in Cunge, et al. (1980).
This document provides guidance on the engineering aspects of applying HEC-6; it is, therefore, a
supplement to the HEC-6 User's Manual. Originally published in 1981, this edition contains substantial
new material based on program enhancements and applications experience gained since then.
This document was prepared by D. Michael Gee, Training Division, HEC. William A. (Tony)
Thomas, Hydraulics Laboratory, WES, provided most of the concepts and material included herein. Vern
Bonner was Chief, Training Division and Darryl W. Davis, Director, HEC, during preparation of this report.

I am not an engineer but an architect. Our profession has been hit by the recession pretty hard. A lot of us were fired, and the generally the situation is at the average level pretty harsh.
I was wondering if we can share some experiences in these times, about the recession related to engineers.
Optimal Steel Fiber Strength for Reinforcement of Cementitious Materials
Authors: Christopher K. Y. Leung and Nathan Shapiro,
ASCE Journal of Materials in Civil Engineering, Volume 11, pp. 116-123 (May 1999)
ISSN: 19435533 (online); 08991561 (print)
ABSTRACT
Steel fiber is the most common type of fiber reinforcement in cementitious materials. The reinforcement efficiency, in terms of maximum crack bridging force and total energy absorption during fiber pullout, is a function of many parameters including the properties of fiber, matrix, and interface as well as fiber size, volume fraction, geometry, and distribution. In this investigation, we focus on the effect of fiber yield strength on reinforcement efficiency. Fiber pullout specimens are fabricated with fibers of different yield strengths. Because cracks in a concrete member may intersect fibers at different angles, pullout tests are carried out with the fiber inclined at 0, 30, and 60°. The experimental results indicate the existence of an optimal fiber yield strength for the maximization of pullout load and pullout work. Inspection of the pullout curves as well as microscopic studies show that a higher fiber yield strength will result in more severe matrix spalling around the fiber exit point, thus limiting the further improvement in reinforcement efficiency. The results confirm the qualitative trend predicted by an existing theoretical model and indicate that the fiber yield strength is an important parameter that should not be overlooked in the design of fiber reinforced cementitious composites.

Bentley SewerCAD v8i (SELECT series 2) 08.11.02.49
(30 Days Trial)
SewerCAD V8i is an extremely powerful program for the design and analysis of gravity flow and pressure flow through pipe networks and pumping stations. The program can be run in Microstation, AutoCAD, and ArcGIS modes, giving you all the power of Microstation and AutoCAD's capabilities, or in Stand-Alone mode utilizing our own graphical interface.
SewerCAD V8i allows you to construct a graphical representation of a pipe network containing information such as pipe data, pump data, loading, and infiltration. You have a choice of conveyance elements including circular pipes, arches, boxes and more.
The gravity network is calculated using the built-in numerical model, which utilizes both the direct step and standard step gradually varied flow methods. Flow calculations are valid for both surcharged and varied flow situations, including hydraulic jumps, backwater, and drawdown curves. You also have the flexibility to mix gravity and pressure components freely, building your systems in parallel or in series as they exist in the field. Pressure elements can be controlled based on system hydraulics, turning pumps on and off due to changes in flows and pressures.
Trial VIP see in your section how to renew the Bentley Trials.
