DOI: 10.1016/j.engfracmech.2021.107740
Abstract: Abstract During the past couple of decades, modern fracture criteria have been developed based on a crack-tip material length scale so-called the critical distance, where the critical energy/stress/strain parameter required for the crack propagation is… read more here.

DOI: 10.1016/j.ijfatigue.2020.105656
Abstract: Abstract The theory of critical distances is based on the definition of a material-dependent length L. Here, we investigate the statistical properties of L deduced from the crack threshold or a suitable notched specimen geometry.… read more here.
