It is now three years since Elsevier Science published the first book of Failure Analysis Case
Studies selected fiom volumes 1,2 and 3 of the journal Engineering Failure Analysis. The book
has proved to be a sought-after and widely used source of reference material to help people avoid
or analyse engineering failures, design and manufacture for greater safety and economy, and
assess operating, maintenance and fitness-for-purpose procedures.
“Why me?”, “It is hard to stay focused”, “I am overloaded with work”, “I even have no time to
breath!” or “My work is boring and degrading”… These are the phrases we usually hear around
the workplace or even from ourselves. They are accompanied by headaches, insomnia…The sign
of depression –“stress” in modern life, appears when work and life tense us up and make us
tired. For the positions that are constantly put under pressure such as the manager, securities
This is mainly applicable for short-lived devices where very large overloads may occur at low cycles. Typical examples include the elements of control systems in mechanical devices. A fatigue failure mostly begins at a local discontinuity and when the stress at the discontinuity exceeds elastic limit there is plastic strain. The cyclic plastic strain is responsible for crack propagation and fracture. Experiments have been carried out with reversed loading and
Whether a terrorist attack, fibre cut, security breach, natural disaster or traffic overload, today's networks must be designed to withstand adverse conditions and provide continuous service. This comprehensive, leading-edge book reveals the techniques and strategies to help you keep enterprise data and voice networks in service under critical circumstances. You learn numerous ways to minimize single points of failure through redundancy and backups, and discover how to select the right networking technologies to improve survivability and performance....
Containing Network Overload
Network designers like think that their traffic models ideally stable, andthat their forecasts to are of future traffic will never be wrong.In real life, however, such assumptions are unwise, because any one of a number of problems may arise, resulting in network overload, and so congestion. The forecast may underestimate demand; there may be a short period of extraordinarily high pressure (for example at New Year, Christmas, or any public holiday, or following a natural disaster); or there may be a network link switch (exchange) failure. ...
Blood components are excellent volume expanders, and transfusion may quickly lead to volume overload. Monitoring the rate and volume of the transfusion and using a diuretic can minimize this problem.
Refrigerated (4°C) or frozen (–18°C or below) blood components can result in hypothermia when rapidly infused. Cardiac dysrhythmias can result from
exposing the sinoatrial node to cold fluid. Use of an in-line warmer will prevent this complication.
