The conditions required for a cohesive zone model (CZM) to predict
a failure load of a cracked structure similar to that obtained by a
linear elastic fracture mechanics (LEFM) analysis are investigated
in this paper. This study clarifies why many different
phenomenological cohesive laws can produce similar fracture
predictions. Analytical results for five cohesive zone models are
obtained, using five different cohesive laws that have the same
cohesive work rate (CWR-area under the traction-separation curve)
but different maximum tractions. The effect of the maximum traction
on the predicted cohesive zone length and the remote applied load
at fracture is presented. Similar to the small scale yielding
condition for an LEFM analysis to be valid. the cohesive zone
length also needs to be much smaller than the crack length. This is
a necessary condition for a CZM to obtain a fracture prediction
equivalent to an LEFM result.
