RESEACH OF THREE-DIMENSIONAL CRACK GROWTH BASED ON DISK OF TURBO-SHAFT ENGINE

open access: yesJixie qiangdu, 2018
Three-dimensional crack growth was analyzed using damage tolerance design-based method and Franc3D to find cause of unexpected fatigue test failure of a turboshaft engine disk,showing that the crack propagation life was shorter than the test inspection ...

Accounting for non-linear effects in fatigue crack propagation simulations using FRANC3D

open access: yes, 2014
In this thesis methods to account for non-linear effects in fatigue crack propagation simulations using FRANC3D are evaluated. FRANC3D is a crack growth software that supports automated crack growth in the FE mesh using the power of an external FE code.

Investigation of Stress Intensity Factors in Welds of Steel Girders Within Steel–Concrete Composite Structures

open access: yesBuildings
Fatigue damage in steel–concrete composite structures frequently initiates at welded joints due to stress concentrations and inherent defects. This study investigates the stress intensity factors (SIFs) associated with fatigue cracks in the welds of ...

Simulation of Railroad Crack Growth Life under the Influence of Combination of Mechanical Contact and Thermal Loads [PDF]

open access: yesInternational Journal of Railway Research, 2015
One of the most important issues in railroad wheels is residual stresses. It is desirable to produce less residual stresses when possible and to decrease the remaining residual stresses in the wheels.
