The mechanics of crack initiation and propagation beneath a moving sharp indentor
The mechanics of crack initiation and propagation beneath a moving sharp indentor is investigated. Stresses generated beneath the indentor for selected horizontal-to-vertical load ratios are used in conjunction with an appropriate fracture mechanics solution to predict the propagation depth of penny...

| Zusammenfassung: | The mechanics of crack initiation and propagation beneath a moving sharp indentor is investigated. Stresses generated beneath the indentor for selected horizontal-to-vertical load ratios are used in conjunction with an appropriate fracture mechanics solution to predict the propagation depth of penny cracks. Results predicted by the model are compared to those obtained in single point scratching and grinding experiments with soda lime glass. |
