11. Modeling flat to slant fracture transition in CTOA specimens using the computational cell methodology
Published: 2/23/2013
Authors: Christopher N McCowan, Jacques Besson, Elizabeth S Drexler
Abstract: Macroscopicmode I ductile crack propagation in thin metallic sheets often starts in mode I as a flat triangle whose normal corresponds to the loading direction. After some limited extension, the crack becomes slanted and propagates under local mixed ...

12. FATIGUE CRACK GROWTH OF TWO X52 PIPELINE STEELS IN A PRESSURIZED HYDROGEN ENVIRONMENT
Published: 9/9/2012
Authors: Andrew J Slifka, Elizabeth S Drexler, Neha N. Rustagi, Damian S Lauria, Joseph David McColskey, Robert L Amaro
Abstract: Fatigue crack growth tests were conducted on two API 5L X52 pipeline steel alloys. One alloy was from a new linepipe that was installed for hydrogen service in 2011. The other alloy was from a vintage pipe that first saw natural gas service in 1964. ...

13. Interpretation and significance of reverse chevron-shaped markings on fracture surfaces of API X100 pipeline steels
Published: 8/15/2012
Authors: Christopher N McCowan, Elizabeth S Drexler, Jeffrey W Sowards
Abstract: Fracture surfaces of X100 pipeline steels were examined with optical and electron microscopy following fracture testing. The fractures show chevron-like fracture patterns, but are distinctly different from classic chevron fracture. The chevron-li ...

14. Ductile-Fracture Resistance in X100 Pipeline Welds Measured with CTOA
Published: 12/1/2011
Authors: Elizabeth S Drexler, Philippe P. Darcis, Christopher N McCowan, Jeffrey W Sowards, Joseph David McColskey, Thomas A. (Thomas A.) Siewert
Abstract: A test for evaluation of resistance to ductile fracture (crack tip opening angle, CTOA) was found to reveal changes in crack propagation through the strain and strength gradients near weld joints in X100 pipeline steels. This test provides a long lig ...

15. AGING-INDUCED ANISOTROPY OF MECHANICAL PROPERTIES IN STEEL PRODUCTS: IMPLICATIONS FOR THE MEASUREMENT OF ENGINEERING PROPERTIES
Published: 9/16/2011
Authors: Mark D. Richards, Elizabeth S Drexler, James R Fekete
Abstract: Strain aging in low-carbon steels is a well-known strengthening phenomenon, the typical results of which are an increase in yield stress and/or an increase in the extent of discontinuous yielding. Aging effects are generally characterized through th ...

16. Fracture of X100 Pipeline Steel: Combined Experimental-Numerical Process
Published: 8/26/2011
Authors: Mordechai Szanto, Christopher N McCowan, Elizabeth S Drexler, Joseph David McColskey
Abstract: Accurate characterization of material fracture properties is necessary for reliable numerical prediction of rupture in gas pipelines. In the current work the ductile fracture properties for high strength X100 pipeline steel, was evaluated, using expe ...

17. MEASUREMENT OF CTOA OF PIPE STEELS USING MDCB AND DWTT SPECIMENS
Published: 9/27/2010
Authors: Christopher N McCowan, S. Xu, W. R. Tyson, R. Eagleson, Elizabeth S Drexler, J. David McColskey, Philippe P. Darcis
Abstract: Two types of specimen for crack tip opening angle (CTOA)measurement have been investigated for pipeline applications,i.e., the modified double cantilever beam (MDCB) (at NIST)and the drop-weight tear test (DWTT) specimen (at CANMET). Results of effe ...

18. SE(T) Testing of Pipeline Welds
Published: 9/27/2010
Authors: Elizabeth S Drexler, Yong-Yi Wang, Jeffrey W Sowards, Marc Dvorak
Abstract: Single edge-notch tension (referred to as SE(T) or SENT) tests are increasingly being used in the pipeline community, as they are a laboratory-scale fracture toughness test, capable of being performed on linepipe steels and welds. The constraint and ...

19. Crack tip opening angle: applications and developments in the pipeline industry
Published: 7/1/2009
Authors: Elizabeth S Drexler, Philippe Darcis, Richard Joel Fields, Joseph David McColskey, Christopher N McCowan, Roni Reuven, Thomas A. (Thomas A.) Siewert
Abstract: One of the most difficult safety problems associated with gas pipeline to be solved is the control of ductile fracture propagation. To address this issue, the crack tip opening angle (CTOA) criterion is becoming one of the more widely accepted proper ...

20. Quantifying Anisotropic Elastic Material Properties of Biological Tissue Using Membrane Inflation
Published: 2/9/2009
Authors: Elizabeth S Drexler, J. E. Bischoff
Abstract: Determination of material parameters for soft tissue frequently involves regressing material parameters for nonlinear, anisotropic constitutive models against experimental data from heterogeneous tests.  Here, parameter estimation using results ...
