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,

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.

Spherical voids by finite fracture mechanics
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’

A new chart of hydraulic fracture height prediction based on fluid–solid coupling equations and rock fracture mechanics [PDF]
Royal Society Open Science, 2018 The conventional method to predict hydraulic fracture height depends on linear elastic mechanics, and the typical Gulrajani–Nolte chart fails to reflect fracture height when the net pressure in the fracture is too high.

Numerical modeling of thermally-induced fractures in a large rock salt mass
Journal of Rock Mechanics and Geotechnical Engineering, 2018 Numerical modeling of thermally-induced fractures is a concern for many geo-structures including deep underground energy storage caverns. In this paper, we present the numerical simulation of a large-scale cooling experiment performed in an underground ...
