Fracture Mechanisms in Polymeric Materials
Fracture Mechanisms in Polymeric MaterialsThe mechanisms of plastic deformation and fracture of polymeric materials are fundamentally different from those in ceramics and metallic materials. This is a consequence of the underlying molecular architecture. Polymers consist basically of long carbon chains, from 1000 to 100,000 atoms, with an extremely strong bond between the carbon atoms.32 The structure is illustrated schematically in Fig. 3.89. The bond between chains is relatively weak. However, interchain strength depends on the complexity of the molecule, being affected by cross-linking and the specif…
