Fatigue-crack-initiation numerical modelling of a Ni-base powder metallurgy alloy
fatigue-crack-initiation numerical simulation slip system powder metallurgy Voronoi tessellation
2014/5/21
A simplified three-dimensional numerical model was presented to simulate the micro-crack nucleation and growth to some predefined dimension (approximately 0.38mm) on the throat surface of a Ni-base po...
Fatigue Crack Growth Behaviour of 6013 Aluminium Alloy at Different Ageing Conditions in Two Orientations
Fatigue Crack growth rate Aluminium alloy Ageing AA6013
2009/10/9
The effect of different ageing treatments on the fatigue crack growth behaviour of AA6013 aluminium alloy was investigated. C(T) (Compact Tension) specimens prepared in L-T and T-L orientations were a...
