Abstract

The morphology of the fracture surface of polymethylmethacrylate (PMMA) is interpreted to show that dynamic fracture of PMMA is predominantly by microcrack nucleation and coalescence. A numerical simulation using a very simple nucleation and growth model for the microcracks is shown to duplicate the fracture surface morphology adequately. These results are then interpreted to indicate the onset of a periodic banding morphology that is typically observed in PMMA.
