Assuming that residual stress-induced effects are simply proportional to density changes, residual densification fields are obtained. The density gradient is nearly isotropic, confirming earlier optical observations made on a similar glass. The results show that Brillouin micro-spectroscopy opens the way to a fully quantitative comparison of experimental data with predictions of mechanical models for the identification of a constitutive law. %G English %2 https://hal.science/hal-00703871/document %2 https://hal.science/hal-00703871/file/Micro-Brillouin%20spectroscopy%20mapping_1203.3046.pdf %L hal-00703871 %U https://hal.science/hal-00703871 %~ ESPCI %~ CNRS %~ UNIV-MONTP2 %~ PMMH %~ LCVN %~ PARISTECH %~ L2C %~ USART %~ LPMMH %~ PSL %~ MIPS %~ UNIV-MONTPELLIER %~ SORBONNE-UNIVERSITE %~ SU-INF-2018 %~ SU-SCIENCES %~ UNIV-PARIS %~ UP-SCIENCES %~ ESPCI-PSL %~ SU-TI %~ ANR %~ ALLIANCE-SU %~ UM1-UM2 %~ UM-2015-2021
