A new chart of hydraulic fracture height prediction based on fluid–solid coupling equations and rock fracture mechanics [PDF]
The conventional method to predict hydraulic fracture height depends on linear elastic mechanics, and the typical Gulrajani–Nolte chart fails to reflect fracture height when the net pressure in the fracture is too high.

FINITE ELEMENT ANALYSIS OF FRACTURE MECHANICS OF WHEEL-RAIL [PDF]
In this paper, wheel-rail contact problem in the presence of rail surface crack is investigated. The reason for investigating this problem is significant effect of wheel-rail contact on stress intensity factors.

Numerical modeling of thermally-induced fractures in a large rock salt mass
Numerical modeling of thermally-induced fractures is a concern for many geo-structures including deep underground energy storage caverns. In this paper, we present the numerical simulation of a large-scale cooling experiment performed in an underground ...

The analysis of bearing capacity of main pipeline in presence of corrosion defects [PDF]
A mathematical model is presented that allows modeling fatigue defects of corrosion origin on main pipelines. A method for assessing the crack resistance of the main pipeline wall with a corrosion defect is proposed.

Investigation of continuum damage mechanics model without element size sensitivity
A discontinuous material behavior such as ductile fracture and fatigue failure is predicted actively in various fields by FEM. There is continuum damage mechanics as a method to evaluate the discontinuous material behavior in a framework of continuum ...

Crack propagation modeling of strengthening reinforced concrete deep beams with CFRP plates
Fracture analysis of reinforced concrete deep beam strengthened with carbon fiber-reinforced polymer (CFRP) plates was carried out. The present research aimed to discover whether crack propagation in a strengthened deep beam follows linear elastic ...

From finite to linear elastic fracture mechanics by scaling [PDF]
The authors describe the asymptotic behaviour of the propagation of a crack in a 2D brittle material. Let \(\Omega \) be a bounded, open and connected domain in \(\mathbb{R}^{2}\) whose Lipschitz boundary \(\partial \Omega \) may be decomposed as the disjoint union \(\partial _{D}(\Omega )\cup \partial _{N}(\Omega )\), with positive Hausdorff measure \(
