Peculiarities of hydraulic fracture propagation in media with heterogeneous toughness: the energy balance, elastic battery and fluid backflow

Daniel Peck, Gaspare Da Fies, Ivan Virshylo +1

This paper investigates hydraulic fracture in a media with periodic heterogeneous toughness. Results for the plane-strain (KGD) model are analysed. The energy distribution as the f…

Averaging-based approach to toughness homogenisation for radial hydraulic fracture

Gaspare Da Fies, Martin Dutko, Daniel Peck

The homogenisation of the fracture toughness is considered in the context of a propagating hydraulic fracture. The radial (penny-shape) model is utilized, in order to incorporate t…

Impact of the tangential traction for radial hydraulic fracture

Daniel Peck, Gaspare Da Fies

The radial (penny-shaped) model of hydraulic fracture is considered. The tangential traction on the fracture walls is incorporated, including an updated evaluation of the energy re…

A temporal-averaging based approach to toughness homogenisation in heterogeneous material

Gaspare Da Fies, Daniel Peck, Martin Dutko +1

A new approach to defining the effective fracture toughness for heterogeneous materials is proposed. This temporal averaging approach is process-dependent, incorporating the crack…

Energy Release Rate, the crack closure integral and admissible singular fields in Fracture Mechanics

Andrea Piccolroaz, Daniel Peck, Michal Wrobel +1

One of the assumptions of Linear Elastic Fracture Mechanics is that the crack faces are traction-free or, at most, loaded by bounded tractions. The standard Irwin's crack closure i…

Particle velocity based hydrofracturing algorithm for a penny-shaped crack

Daniel Peck, Michel Wrobel, Monika Perkowska +1

A universal particle velocity based algorithm for simulating hydraulic fracture with leak-off, previously demonstrated for the PKN and KGD models, is extended to obtain solutions f…
