Review:Advances in research of stress-assisted corrosion fatigue problem

INTRODUCTION People find that when many glasses and ceramic materials are subject to static loading as well as a chemically reactive environment, they often experi-ence delayed failure due most likely to stress-assisted chemical reactions at the cracks: pre-existing surface flaws grow to a critical length, at which point unstable rapid crack propagation ensues, leading to catastro-phic failure. For a given material and ambient envi-ronment, the lesser the applied stress, the longer the ti…

Review:Advances in research of stress-assisted corrosion fatigue problem

Ceramic materials are notable for their rigidity, insulation and resistance to hostile environment. Nevertheless, if a stressed ceramic component is exposed to chemical attack, it may suffer from a form of delayed fracture known as static fatigue. From the point of view of a designer, it is clearly desirable to determine the behavior of sub-critical crack growth; the crack path and crack growth rate, as a function of material properties and loading conditions are of particular interest. This paper presents a review of advances in stress assisted corrosion problem in history and its corresponding numerical approaches in the last decades, and finally, comes up with consideration and crucial suggestions for future work.
