The theory of critical distances applied to problems in fracture and fatigue of bone [PDF]
Fracture and Structural Integrity, 2009 The theory of critical distances (TCD) has been applied to predict notch-based fracture and fatigue in a wide range of materials and components. The present paper describes a series of projects in which we applied this approach to human bone.

Mean spherical approximation for the Lennard-Jones-like two Yukawa model: Comparison against Monte Carlo data [PDF]
Condensed Matter Physics, 2011 Monte Carlo simulation studies are performed for the Lennard-Jones like two Yukawa (LJ2Y) potential to show how properties of this model fluid depend on the replacement of the soft repulsion by the hard-core repulsion.

Static assessment of brittle/ductile notched materials: an engineering approach based on the Theory of Critical Distances [PDF]
Fracture and Structural Integrity, 2014 Engineering components often contain notches, keyways or other stress concentration features. These features raise the stress state in the vicinity of their apex which can lead to unexpected failure of the component.

Estimation of fretting fatigue life using a multiaxial stress-based critical distance methodology [PDF]
Fracture and Structural Integrity, 2015 This work presents a methodology for life estimation of mechanical couplings subjected to fretting fatigue. In this approach, a stress-based multiaxial fatigue parameter is evaluated at a critical distance below the contact surface. The fatigue parameter

On the use of length scale parameters to assess the static strength of notched 3D-printed PLA [PDF]
Fracture and Structural Integrity, 2017 This paper aims to investigate the accuracy of the Theory of Critical Distances (TCD) in estimating static strength of notched additively manufactured PLA as both notch sharpness and infill angle vary.

Gradient enriched linear-elastic crack tip stresses to estimate the static strength of cracked engineering ceramics [PDF]
Fracture and Structural Integrity, 2013 According to Gradient Mechanics (GM), stress fields have to be determined by directly incorporating into the stress analysis a length scale which that takes into account the material microstructural features.
