Recent progress to understand stress corrosion cracking in sodium borosilicate glasses: linking the chemical composition to structural, physical and fracture properties
... Stress corrosion cracking (SCC) concerns the sub-critical growth of a crack front and occurs when environmental corro- sive agents attack the crack front, thus causing it to propagate [ 1 , 2 ]. Previous literature and ...
