Strategies for rapid parametric assessment of microstructure-sensitive fatigue for HCP polycrystals
TL;DR: In this paper, the feasibility of estimating the mesoscale strain fields in hexagonal close packed (HCP) α -titanium polycrystals during HCF loading conditions using the computationally low-cost Materials Knowledge System (MKS) approach, and subsequently estimating the slip system activities via decoupled numerical integration of relevant crystal plasticity constitutive relations.

LCF, HCF and VHCF life sensitivity to solution heat treatment of a third-generation Ni-based single crystal superalloy
Luciana Maria Bortoluci Ormastroni,Lorena Mataveli Suave,Alice Cervellon,Patrick Villechaise,Jonathan Cormier +4 more
TL;DR: In this article, the fatigue life variability of a newly developed third-generation Ni-based single crystal superalloy resulting from different solution heat treatment procedures has been investigated in low cycle fatigue (T =※650 °C/Rσ σ 0.05/f σ 1/f f 0.5/f 0.20 kHz), high cycle fatigue, and very high cycle fatigues (T

Strain-energy-density factor applied to mixed mode crack problems
TL;DR: In this paper, the authors investigated the general problem of crack extension in a combined stress field where a crack can grow in any arbitrary direction with reference to its original position, and showed that the direction of crack growth and fracture toughness for the mixed problem of Mode I and Mode II are governed by the critical value of the strain-energy-density factor.
