Abstract:
The strain evolution and distribution during an aluminum alloy AlSi9Cu3 casting were monitored with the arrays of optical fiber Bragg grating sensors. A high degree of correlation was found between the solidification phases of the aluminum alloy and the strain behavior during casting. A gradient strain distribution after solidification, which might be related to the residual stresses, was further revealed. The final compressive strain reached −10,000 microstrains due to the shrinkage of the alum...     »
