“…In [15,35], the variation of G Ic with crack velocity was assumed to be either linear, bi-linear or parabolic until a good prediction of the stick-slip behaviour was achieved. In [36] stick-slip propagation was not explicitly modelled and the values of G Ic deduced were based on an analytical energy approach [18], and the effect of loading rate on the value of G Ic was discussed in terms of a adiabatic thermal-heating model (ATM) [36]. In [37,38], a nonmonotonic fracture energy versus crack velocity curves were postulated.…”

“…15,[32][33][34][35][36]. In order to predict stick-slip behaviour using a FEA CZM approach, Sun et al [32,33] assumed an initial region ahead of the crack tip with a CZM toughness much higher than that in the rest of the specimen (i.e.…”

Tapered-double cantilever-beam joints were manufactured from aluminium-alloy substrates bonded together using a single-part, rubber-toughened, epoxy adhesive. The mode I fracture behaviour of the joints was investigated as a function of loading rate by conducting a series of tests at crosshead speeds ranging from 3.33 x10 -6 m/s to 13.5 m/s. Unstable, (i.e. stick-slip crack) growth behaviour was observed at test rates between 0.1 m/s and 6 m/s, whilst stable crack growth occurred at both lower and higher rates of loading. The adhesive fracture energy, G Ic , was estimated analytically, and the experiments were simulated numerically employing an implicit finite-volume method together with a cohesive-zone model. Good agreement was achieved between the numerical predictions, analytical results and the experimental observations over the entire range of loading rates investigated. The numerical simulations were able very readily to predict the stable crack growth which was observed, at both the slowest and highest rates of loading. However, the unstable crack propagation that was observed could only be predicted accurately when a particular rate-dependent cohesive zone model was used. This crack-velocity dependency of G Ic was also supported by the predictions of an adiabatic thermal-heating model (ATM).

“…Although the crack length correction cannot be used without measuring the load, it only depends on the elastic properties of the adherend [10]. Therefore, the calculated value of |Δ| from the average value in the quasi-static tests was applied to calculate the impact test results.…”
