On the similarity methods in fracture mechanics [PDF]
, 1998 This paper presents a brief review about the application of similarity methods to fracture mechanics. This includes some dimensionless numbers and some scaling laws in fracture mechanics, discrete scale invariance (DSI) and log-periodic corrections to ...

Dental Materials, 1995 The principles of linear elastic fracture mechanics (LEFM) were developed in the 1950s by George Irwin (1957). This work was based on previous investigations of Griffith (1920) and Orowan (1944). Irwin (1957) demonstrated that a crack shape in a particular location with respect to the loading geometry had a stress intensity associated with it.

Experimental characterization and numerical modeling of micromechanical damage under different stress states [PDF]
, 2013 The use of HSLA steels for the manufacture of automotive components is interesting from an engineering point of view. This family of steels, while possessing high strength, also has good formability and can be used in forming manufacturing processes.

The Archimedes’ Constant, π Seen by Mechanical Engineers
Mathematical and Computational Applications, 2019 Probabilistic engineering mechanics is used to relate the value of π with one of the main parameters in fracture mechanics. It proposes an engineering method to obtain the value of it from engineering data without involving any geometrical ...

Fracture analysis of debonding mechanism for FRP plates [PDF]
, 2009 Inevitable flaws in the concrete-FRP interface govern plate debonding, and are not amenable to finite element analysis because the models require far more detail than will ever be available for the interface. This thesis describes a global-energy-balance

Modified Fracture Mechanics Approach for Hydraulic Fracturing Stress Measurements
Geofluids, 2020 Hydraulic fracturing (HF) test has been widely used to determine in situ stress. The use of a conventional continuum method for this purpose has raised considerable controversies concerning field tests, particularly in the determination of the maximum ...
