Strength of glass determined by the relation of the critical flaw to the fracture mirror

Jean-Paul Lebet, Maria Lindqvist

Tensile strength of structural glass elements is highly influenced by flaws. For this paper, the study concentrates on the fracture origin i.e. the critical flaw, situated at the edge of a glass element. In the current study the influence of two different ...
