Analysis of fatigue fractures in polymethyl methacrylate during bending in combination with rotation — Part I

This examines the fracture surfaces in polymethyl methacrylate (PMMA) obtained during fatigue testing of small specimens with round console bending in the presence of a heating hysteresis. It is shown that the accumulation of damage at all stages of the process of fatigue breakdown, as in the case of stabilized temperatures, has a scatter failure characteristic.
