Fracture Mechanics (SIAM-AMS Proceedings, Volume XII)

Fracture mechanics

In this article, after a brief description of some signi®cant catastrophic structural failures going back to the period when iron and steel began to replace wood and masonry as the primary structural materials, the historical development of the ®eld of fracture mechanics is discussed. First, the basic concepts of the ®eld, the motivation underlying their development and the key contributions ma...

FRACTURE MECHANICS WHAT IS FRACTURE MECHANICS Fracture mechanics is mechanics of solids containing planes of displacement discontinuities (cracks)

Volume XII ROENTGENOGRAPHIC SCANNING OF THE CHEST

Of all the roentgen examinations, that of the chest is best. Its position is the easiest; it seldom requires contrast media, it is by far the most productive in demonstration of abnormalities; and with the exception of bone films it offers the greatest detail. It has been such a tremendously important tool to medicine that there is a tendency to consider it infallible. However, in the compariso...

Fracture mechanics-based life prediction of a riveted lap joint

In this paper, three-dimensional modeling of the fatigue crack growth profiles was performed in a simple riveted lap joint. Simulation results showed that mode I was dominated on the one side of the plates and the crack straightly grew on this side, while the other side of the plates was in a mixed-mode condition and the crack propagation path was not straight on this side. Afterward, the fract...

Cracks Analysis in Zavin Concrete Dam Using Fracture Mechanics Approach

Most of the existing concrete dams are subjected to cracking. These cracks are caused by various factors such as construction practices, curing, loads and volume change of mass concrete which reduce the efficiency, failure or instability of concrete dams. Using fracture mechanics as a new method to estimate stability and durability of concrete dams is recommended in scientific publications in w...
