Features of quasi-brittle fracture of polymers and composites based on them

Abstract

Measurements of the crack's rostrum and strength in rostrum are defined. Form and measurements of constrained elasticity growing up in amorphous solid polymers in front of destruction crack at the temperatures higher then fragility temperature are defined/ Movement of the crack with zone of elasticity is investigated in a computer experiment. The processes of heat release in development of the zone of constrained elasticity are investigated.
