Crack growth threshold under hold time conditions in DA Inconel 718 – A transition in the crack growth mechanism

E. Fessler, S. Pierret, E. Andrieu, V. Bonnand

Aeroengine manufacturers have to demonstrate that critical components such as turbine disks, made of DA Inconel 718, meet the certification requirements in term of fatigue crack growth. In order to be more representative of the in service…

Modeling of the transition from transgranular to intergranular fracture at elevated temperatures in EI698 nickel alloy

Andrey Tumanov

In this study, an efficient computational method for modeling the transition from transgranular to intergranular fracture mechanisms based on phase field fracture theory is discussed. Structural heterogeneity of the material is modeled on…
