摘要
Fracture behavior of polymer materials employed in stomatologic practice for preparing provisional constructions is examined. Fracture patterns in polymers are shown to be alternating (ductile, ductile-brittle, brittle) under loading. Fracture patterns of those materials in quasistatic tension were evaluated by criterion parameter values, they were ranged by the brittleness characteristic.
