H.H. Kausch, Crazing in Polymers

The use of polymer glasses to make structural components has increased significantly over the last decade but is still limited by the tendency of these materials to fail in a macroscopically brittle manner (i.e., with no large scale plastic deformation before cracking). The brittleness can be traced to the formation under tensile stress of small crack-like defects called crazes. Unlike cracks, these are load bearing because their two surfaces are bridged by many small fibrils with diameters in the range 5 to 30 nm.
