Finite Fracture Mechanics at elastic interfaces
International Journal of Solids and Structures, 2012 AbstractIn the present paper we provide a method to determine the load causing delamination along an interface in a composite structure. The method is based on the elastic interface model, according to which the interface is equivalent to a bed of linear elastic springs, and on Finite Fracture Mechanics, a crack propagation criterion recently proposed ...

Finite similitude in fracture mechanics [PDF]
Engineering Fracture Mechanics, 2021 Scaled experimentation can potentially provide significant benefits such as reduced costs materials and time in testing but is afflicted by the phenomena of scale effects, where the behaviour at scale can be markedly different to that at full size. The design of scaled experiments is presently predominantly founded on the theory of dimensional analysis,

Spherical voids by finite fracture mechanics [PDF]
Procedia Structural Integrity, 2021 Abstract The apparent weakening of a uniaxially tensioned infinite domain that contains a single spherical void and is anywhere else filled with a homogeneous and linear elastic material is investigated through two Finite Fracture Mechanics approaches. Resultant charts depicting the respectively predicted relation of the weakening ratio with the void’

Fatigue crack onset by Finite Fracture Mechanics [PDF]
Procedia Structural Integrity, 2019 Abstract The paper investigates the fatigue crack/notch sensitivity by the coupled criterion of Finite Fracture Mechanics (FFM). The approach involves two parameters: the plain specimen fatigue limit, and the threshold value of the stress intensity factor range for fatigue crack growth. Useful analytical relationships are presented.

Penny-shaped cracks by Finite Fracture Mechanics
International Journal of Fracture, 2019 In this brief note, we provide the failure stress of a solid containing a penny-shaped crack by means of Finite Fracture Mechanics. The solution is analytical up to the numerical root of the equation providing the finite crack growth increment. Results are discussed and compared with the ones provided by Linear Elastic Fracture Mechanics, by Theory of ...

Applied Sciences, 2021 Problems in fracture mechanics are difficult when the appropriate analysis is unspecified, which is very common in most real-life situations. Finite element modeling is thus demonstrated to be an essential technique to overcome these problems.
