The stability of critical distance theory model for high cycle fatigue limit prediction of foreign object damaged blade samples [PDF]
Scientific ReportsFan and compressor blades are the critical components of aircraft engine. During flight operations, aircraft engines are inherently susceptible to ingesting debris, resulting in foreign object damage (FOD) that compromises structural integrity of fan and

Critical length parameter of HDPE and its use in fatigue lifetime predictions
Fracture and Structural IntegrityThe contribution describes the fatigue lifetime predictions of polyethylene notched specimens based on the theory of critical distance. The approach uses the line method, which averages the axial stress over the critical distance.

Applications of the theory of critical distances in failure analysis [PDF]
Engineering Failure Analysis, 2011 Abstract The Theory of Critical Distances (TCD) is the name which I use to describe a group of methods employed for the prediction of failure in cases where stress concentrations are present and where the failure mode involves cracking, such as fatigue and brittle fracture. Some of these methods are more than 50 years old, some very recent.

Comparing distance bounding protocols: A critical mission supported by decision theory [PDF]
Computer Communications, 2015 Distance bounding protocols are security countermeasures designed to thwart relay attacks. Such attacks consist in relaying messages exchanged between two parties, making them believe they communicate directly with each other. Although distance bounding protocols have existed since the early nineties, this research topic resurrected with the deployment

THEORY OF CRITICAL DISTANCES AND THE THICKNESS OF THE SURFACE LAYER
, 2023 The theory of critical distances is based on the strength of materials L, which is given by its strength properties KIc and σ0. We have shown that the thickness of the surface layer R(I) is equal to the nanocrack length Lnm. We have shown that there is a relationship between L and Lnm: L = 104 Lnm = 104 R(I) ≈ 10-5 М/ρ.

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.
