Plastic Zone Radius Criteria for Crack Propagation Angle Evaluated with Experimentally Obtained Displacement Fields

Buildings
The monitoring and maintenance of cracked structures are generally carried out using structural integrity assessments. The plastic zone (PZ) crack path (CP) criteria state that a crack grows in a specific direction when the radius of the plastic zone ...

On the use LEFM, NLFM and CZM in the analysis of a DCB test [PDF]

, 2019
Double cantilever beam (DCB) is the standard specimen for determining fracture resistance in mode I. This is usually done by using simple data-reduction schemes that combine linear- elastic fracture mechanics (LEFM) and beam theory (either Euler-Bernoulli or Timoshenko).

Residual strength evaluation by DBEM for a cracked lap joint

Fracture and Structural Integrity, 2015
The present work summarizes a numerical procedure aimed at the evaluation of the residual strength of a cracked lap joint, based on the competing failure mechanisms regulated by the R-curve analysis and plastic collapse.

Repair interface crack resistance mechanism: A case of magnesium phosphate cement overlay repair cement concrete pavement surface

Developments in the Built Environment
Cement concrete pavements are continuously impacted by environment and vehicle loads, resulting in corner cracking, pockmarked surface and other distresses. It emerges a hot topic: reinforcement and repair.

Williams expansion-based approximation of the stress field in an Al 2024 body with a crack from optical measurements [PDF]

Fracture and Structural Integrity, 2017
A study on the approximation of the stress field in the vicinity of crack tip in a compact tension specimen made from Al 2024-T351 is presented. Crack tip stress tensor components are expressed using the linear elastic fracture mechanics (LEFM) theory in

The influence of the shape of a saw-cut notch in quasi-brittle 3PB specimens on the critical applied force [PDF]

Applied and Computational Mechanics, 2008
Values of fracture parameters of quasi-brittle building materials are usually determined from results of tests performed on notched testing specimens. The contribution deals with the influence of various shapes of tips of notches prepared by a diamond ...

Reevaluating brittleness in material selection: Why fracture toughness alone is insufficient

Materials & Design
Material selection methods commonly rely on fracture toughness attribute limits to screen out brittle materials. However, this approach can lead to overly restrictive exclusions of ductile materials with low toughness and the unintended inclusion of high-

Assessment of structural integrity of subsea wellhead system: analytical and numerical study

Fracture and Structural Integrity, 2014
Subsea wellhead systems exposed to severe fatigue loading are becoming increasingly a significant problem in offshore drilling operations due to their applications in wells with higher levels of pressure and temperature, situated at larger depths and in ...
