Grain boundary energies and cohesive strength as a function of geometry
, 2008 Cohesive laws are stress-strain curves used in finite element calculations to describe the debonding of interfaces such as grain boundaries. It would be convenient to describe grain boundary cohesive laws as a function of the parameters needed to ...

Comparison between natural fractures and fracture parameters derived from VSP [PDF]
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1991 SUMMARY The feasibility of resolving a subsurface fracture system using P-wave and cross-polarized shear-wave vertical seismic profiling (VSP) was examined. In situ distributions of fractures and microcracks in a test borehole are characterized by an ultrasonic borehole televiewer (BHTV) and by measurements of core sample velocities.

Fracture mechanics parameters of multilayer pipes [PDF]
Applied and Computational Mechanics, 2007 Multilayer pipes consisting of different materials are frequently used in praxis because of partial improvement of the properties of pipe systems. To estimate lifetime of these pipes the basic fracture parameters have to be determined.

Chemical fracture and distribution of extreme values
, 2002 When a corrosive solution reaches the limits of a solid sample, a chemical fracture occurs. An analytical theory for the probability of this chemical fracture is proposed and confirmed by extensive numerical experiments on a two dimensional model.

High-accuracy phase-field models for brittle fracture based on a new family of degradation functions [PDF]
, 2017 Phase-field approaches to fracture based on energy minimization principles have been rapidly gaining popularity in recent years, and are particularly well-suited for simulating crack initiation and growth in complex fracture networks.
