Fracture evolution during indentation of a brittle elastic solid

Proppant-Induced Opening of Hydraulically Created Fractures

“…2 A.P.S. Selvadurai, Proppant-Induced Opening of Hydraulically Created Fractures that can result from the interaction of the poroelastic rock with the non-deformable granular proppant zones possibly leading to indentational brittle fracture [Selvadurai, 2000a] and indentation damage [Selvadurai, 2004, Selvadurai andShirazi, 2004] at contact zones. It should be emphasized that Eq.…”

Indentation of a surface-stiffened elastic substrate

“…The surface reinforcement of substrates is important to several areas of material science and engineering in order to enhance abrasion resistance, minimize deformation at contacts and prevent failure development at contact zones 40 . The assessment of the integrity of the bond between the reinforcing layer and the substrate can be performed using both static and dynamic indentation tests and wave propagation tests.…”

Using the discrete element method to simulate brittle fracture in the indentation of a silica glass with a blunt indenter

“…This result was first observed by Hertz (11,12). This phenomena has been intensively studied; however, computational models are still in discussion (13,14,15,16,17). The objective of this paper is to investigate DEM as an effective alternative for studying complex cracking phenomena such as the hertzian cone crack.…”
