WebThe citations to Griffith crack theory are numerous, with roughly 30 annually more than a century after publication. Maybe less well known is the fact that Griffith invented a new material. He was studying cracks in glass, then began to test the strength of glass fibers, which he drew manually from a white-hot bead. WebMar 10, 2024 · D.W.
