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)

SPECIALISTS 1ffiETING ON ELASTOPLASTIC FRACTURE MECHANICS

The structural materials used for LMFBR are austeniticsteels from Type AISI 304, 316 or steels which are simi-lar. Investigations show that a leak-be fore-break conceptcan be established for LMFBR piping systems and components,due to the ductile behavior of these steels and the opera-ting conditions. A major element of this concept is theknowledge of fatigue crack growth...

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...
