Crack propagation is considered as a random walk process of consecutive atomic bond breaking and healing steps. The total number of steps is propo~ion~ to tfre propa~t~n time, and the difference of the number of breaking and healing steps is propo~ional to the location of the crack tip at that time.
## Most fatigue crack proration studies reported in the literature have been conducted from either a continuum or micro-mechanics point of view. Attempts to combine these points of view within a single experimental study or modeling effort have been relatively scarce. This is surprising considerin
An extension of the validity of a theory proposed at the Crack Propagation Symposium in Cranfield, September 1961, has been performed by introducing a new parameter, the endurance limit n,, i&o the basic formula, which thus takes the form dx/&? = k(o -a,)@. The relationship between crack length z a
The kinetics theory of thermally activated time dependent crack propagation is extended to describe the crack size dist~but~on in non-steady state. The dis~but~on is represented by a series of n differential equations, each expressing the rate of crack tip concentration change over the system of n c
