On the configurational force associated with blocked slip bands at grain boundaries in α-Ti
Abdalrhaman Koko
Grain boundaries can block slip-band propagation and generate intense local stress and strain fields that influence subsequent deformation and damage initiation in polycrystalline…

In situ elucidation of mechanisms governing crack transition to plasticity arrest
Abdalrhaman Koko, Bemin Sheen, Caitlin Green +1
Despite extensive theoretical treatment of short- to long-crack transitions, direct experimental quantification of how elastic and plastic energy contributions evolve at the crack…

DIC2Abaqus: Calculating mixed-mode stress intensity factors from 2D and 3D-stereo displacement fields
Abdalrhaman Koko, T. James Marrow
Integrating experimental data into simulations is crucial for predicting material behaviour, especially in fracture mechanics. Digital Image Correlation (DIC) provides precise disp…
