The theory of critical distances applied to problems in fracture and fatigue of bone [PDF]
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.

Static assessment of brittle/ductile notched materials: an engineering approach based on the Theory of Critical Distances [PDF]
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]
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]
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]
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.

KIc Determination of a 7075 T6 Aluminum Alloy by Critical Distances Theory and LEFM [PDF]
The Critical Distances Theory has been used in engineering field as a less expensive method to predict failures. Thus, this research aims to evaluate its methods in other materials, like the aluminum alloy 7075 T6, and notches. Two different notches were
