On the Path of a Quasi-static Crack in Mode III [PDF]
A method for finding the path of a quasi-static crack growing in a brittle body is presented. The propagation process is modelled by a sequence of discrete steps optimizing the elastic energy released. An explicit relationship between the optimal growing direction and the parameters defining the local elastic field around the tip is obtained for an ...

Fatigue Crack Paths in Sintered Duplex Stainless Steels
In the present work we considered three different sintered duplex stainless steels. Their fatigue crack propagation resistance was investigated by means of fatigue crack propagation tests according to ASTM E 647 standard, considering three different ...

Nondestructive Testing of Welded Composite Metal Foams
X‐ray computed tomography (CT) is used to evaluate welded steel–steel composite metal foam (CMF) joints of two density classes. It reports variation in postweld spatial void distribution and correlates it to weld‐induced changes, mechanical performance, and failure within welded CMF panels.

Investigation of crack propagation path in tube gears
Abstract In this paper, the crack propagation behaviour in tube gears has been investigated. This kind of gear find application in aerospace and in particular in helicopter drivelines. For this reason, an accurate design against catastrophic failure due to particular crack propagation paths, has to be performed.

A new impact test for the identification of a dynamic crack propagation criterion using a gas-gun device [PDF]
The modelling of damage and fracture behaviour under high rates of loadings for metallic structures presents the more and more interests for engineering design, especially for crash phenomena.In order to perform a numerical simulation of such phenomena a

This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.

Microcrack evolution and permeability enhancement due to thermal shocks in coal.
To understand the effects of thermal shock on microcrack propagation and permeability in coal, thermal shock tests were conducted on coal specimens by using a constant temperature drying oven (105 °C) and a SLX program controlled cryogenic tank.

Propagation of semi-elliptical crack in pin-lug joint
Pin-lug joints are commonly employed to connect components related to several mechanical applications in aeronautic, marine and automotive fields. The load transferred by the pin to the lug, through the contact along the hole edge, generates high local
