TL;DR: In this paper, the dynamics of tensile crack fronts restricted to advance in a plane are studied, and a propagating mode along the crack front with a velocity slightly less than the Rayleigh wave velocity, is found to exist.
Abstract: The dynamics of tensile crack fronts restricted to advance in a plane are studied. In an ideal linear elastic medium, a propagating mode along the crack front with a velocity slightly less than the Rayleigh wave velocity, is found to exist. But the dependence of the effective fracture toughness $\ensuremath{\gamma}(v)$ on the crack velocity is shown to destabilize the crack front if $\frac{d\ensuremath{\gamma}}{\mathrm{dv}}l0$. Short wavelength radiation due to weak random heterogeneities tends to lead to this instability at low velocities. The implications of these results for the crack dynamics are discussed.

TL;DR: Cort cortical bone compartmentalizes the damage morphologies in different regions and the sequence of damage production in different phases of cyclic loading to dissipate energy and resist a catastrophic fracture.

TL;DR: In this article, the mode I constant displacement rate tests were conducted on epoxy-bonded CFRP joints at −50, 22, and 90°C and the critical strain energy release rate was seen to increase with temperature and the failure locus transferred from predominantly in the composite substrate to predominantly in adhesive.
