Experimental and numerical analysis of deformation patterns in notched heterogeneous welds [PDF]
, 2017 Standardized weld flaw assessment techniques assume the weld region to be homogeneous which is a strong idealisation of reality. Characterising the effects of heterogeneous properties of welds through the analysis of deformation patterns and slip lines ...

Influence and evaluation of constraint on fracture toughness in pipeline research [PDF]
, 2012 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

Reproducibility of Pop-Ins in Laboratory Testing ofWelded Joints [PDF]
, 2000 The pop-in phenomenon, quite common in fracture mechanics tests of welded joints, corresponds to a brittle crack initiation grown from a local brittle zone (LBZ) that is arrested in reaching the higher toughness material that surrounds this LBZ.

Tensile and Fracture Mechanical Properties of Styrene-Butadiene Rubbers (SBR) Filled with Industrial and Pyrolytic Carbon Blacks, and Organoclay [PDF]
, 2017 In this work we examined effects of filler combinations (industrial carbon black (CB), pelletized pyrolytic carbon black (pCBp) and organoclay (I30.P) on the tensile mechanical and fracture mechanical properties of SBR rubbers.

Strip Yield Model Numerical Application to Different Geometries and Loading Conditions [PDF]
A new numerical method based on the strip-yield analysis approach was developed for calculating the Crack Tip Opening Displacement (CTOD). This approach can be applied for different crack configurations having infinite and finite geometries, and ...

Finite-element analyses and fracture simulation in thin-sheet aluminum alloy [PDF]
A two-dimensional, elastic-plastic finite-element analysis was used with a critical crack-tip-opening angle (CTOA) fracture criterion to model stable crack growth in thin-sheet 2024-T3 aluminum alloy under monotonic loading after precracking at different

Fracture Assessment of Weld Joints of High-Strength Steel in Pre-Strained Condition
Applied Sciences, 2019 Unstable fractures tend to occur after ductile crack initiation or propagation. In most collapsed steel structures, a maximum 15% pre-strain was recorded, at the steel structural connections, during the great earthquake of 1995, in Japan. Almost-unstable

Elastic plastic fracture behavior and effect of band- overload on fatigue crack growth rate of an HSLA steel [PDF]
, 2014 Study of fracture toughness and fatigue crack growth behavior are important parameters of structural materials. These parameters can be used to predict their life, service reliability and operational safety in different conditions.
