Fracture in Viscoelastic Media
This chapter discusses the analytical extension of Griffith’s work to linearly viscoelastic materials. Through consideration of the simple case of a spherical flaw loaded by hydrostatic tension, it is found that the crack initiation criterion depends on the loading history. The chapter concludes with some remarks on fatigue fracture in elastomers.
