Finite-element analysis (FEA) can be useful for optimising the procedure by predicting residual stresses whose magnitude may be compared to the acceptable value obtained from an ECA. (W 32) (1)

Finite-element analysis = Análise de elementos finitos

In support of understanding the mechanisms responsible for any deficiency in Miner’s rule, fracture-mechanics analysis was carried out by measuring and predicting the crack growth in specimens tested under both Constant Amplitude (CA) and Variable Amplitude (VA) loading.(W 134) (2)

Fracture-mechanics analysis = Análise de fratura-mecânica

In view of the small data set, a stepwise regression analysis was carried out, using Microsoft Excel. (W 342) (3)
