Cold dwell behaviour of TiAl alloy: Understanding load shedding using digital image correlation and crystal plasticity simulations
Yi Xiong, Nicolo Grilli, Phani S. Karamched +3
Digital image correlation (DIC) and crystal plasticity simulation were utilised to study cold dwell behaviour in a coarse grain Ti-6Al alloy at 3 different temperatures up to 230 C…
Crystal plasticity model of residual stress in additive manufacturing
Nicolò Grilli, Daijun Hu, Dewen Yushu +2
Selective laser melting is receiving increasing interest as an additive manufacturing technique. Residual stresses induced by the large temperature gradients and inhomogeneous cool…
Characterisation of slip and twin activity using digital image correlation and crystal plasticity finite element simulation: Application to orthorhombic -uranium
Nicolò Grilli, Philip Earp, Alan C. F. Cocks +2
Calibrating and verifying crystal plasticity material models is a significant challenge, particularly for materials with a number of potential slip and twin systems. Here we use di…
An in-situ synchrotron diffraction study of stress relaxation in titanium: Effect of temperature and oxygen on cold dwell fatigue
Yi Xiong, Phani S. Karamched, Chi-Toan Nguyen +5
There is a long-standing technological problem in which a stress dwell during cyclic loading at room temperature in Ti causes a significant fatigue life reduction. It is thought th…
