Abstract A procedure is outlined for calibrating a finite element model to simulate ductile cracking that employs a continuum damage criterion for ductile fracture initiation, termed the Stress Weighted Ductile Fracture Model, with an Adaptive Cohesive Zone method to simulate crack propagation.

Influence and evaluation of constraint on fracture toughness in pipeline research [PDF]
Accessing nowadays fossil fuel reserves requires a strain-based design approach. Within such design, the ductile tearing resistance is a key parameter in assessing the defect tolerance. To determine this tearing resistance, full scale (pressurized) tests

Crack Propagation Phenomenon in Gangue Concrete Using the Digital Image Correlation (DIC) Method
In order to study the mode I crack propagation mechanism of coal gangue concrete with different contents, the digital image correlation (DIC) method was used to carry out the three‐point bending fracture tests on coal gangue concrete with different contents.

Plastic collapse loads Pc and CTODs of a cracked Circular Hollow Section (CHS) T-joint
The FailureAssessment Diagram (FAD) is an accepted approach in assessing the structural safety and integrity of any cracked tubular joint. In order to extend its application to a more complex geometry of any cracked Circular Hollow Section (CHS) tubular T-joint, there are three major challenges needed to be overcome; firstly there is a need to validate
