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…
Numerical simulation of hydraulic fracturing: a hybrid FEM based algorithm
Michal Wrobel, Panos Papanastasiou, Daniel Peck
In this paper a problem of numerical simulation of hydraulic fractures is considered. An efficient algorithm of solution is proposed for the plain strain model of hydraulic fractur…
A simplified modelling of hydraulic fractures in elasto-plastic materials
Michal Wrobel, Panos Papanastasiou, Daniel Peck
In this paper the problem of a plane strain hydraulic fracture propagating in an elasto-plastic material is analyzed. A new stress redistribution model for the proximity of the fra…
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…
