Fatigue Crack Initiation and Propagation in Piles of Integral Abutment Bridges A new continuum damage modeling approach of "successive initiation" is used to determine the location of a thermomechanical fatigue crack initiation and th... J Razmi,L Ladani,MS Aggour - 《Computer〢ided Civil & ...
To clarify the mechanism of fatigue failure in eutectoid steel, fatigue crack initiation and propagation behaviors have been studied in detail under rotating bending fatigue tests using rail steels. The fatigue failure surface was also examined by using SEM. The main results obtained are as follows;...
Fatigue tests on Zr-based bulk metallic glass were conducted under fully reversed cyclic bending (R=−1), and the surfaces of the fatigued specimen were observed to elucidate the fatigue crack initiation mechanisms. The fracture surface was also observed to examine the crack propagation mechanism....
Fatigue Crack Initiation and Propagation at High Temperature in a Softening Martensitic Steel Martensitic steels of the 9Cr1Mo family have been selected for advanced power generation systems, in particular because of their high thermal conductivity and low thermal expansion coefficient [1]. Typical in-...
The crack initiation and propagation in on-board packaging solder joint during thermal fatigue test was investigated by experimental and numerical method together.In this experiment the lead-less resistance of 3216 and the PCB of FR4 were selected.And two kinds of land shapes and two kinds of sol...
Fatigue crack initiation sites were identified and the microscopic features responsible for crack initiation are illustrated. Differences in the fracture morphology of PMMA beads, in early crack growth and rapid crack growth stages, are brought out. Based on the fractographic features, a micromechanism...
The mechanism of trapped fluid, where the crack mouth closes under the contact pressure and the trapped fluid is driven toward the crack tip; this results in mode I separation at the crack tip, reduction of the crack face friction and increase in the mode II influence on crack propagation. ...
