PIRAMID v.4.5.3 released


We are pleased to announce that PIRAMID™ version 4.5.3 is now available for download.  This release adds the ability to directly specify pipeline fracture toughness when using the API 579 crack model and significantly increases the calculation speed of hydrostatic test scenarios for all structural reliability models.  

  • The API 579 model for crack-like features now accepts either a notch toughness input or direct specification of the pipeline fracture toughness. The model accuracy has also been improved for cases with low defect growth rates.
  • Hydrostatic test scenarios have been updated to substantially reduce simulation time.
  • Minor improvements have been made to the new API that allows models to be called from outside of PIRAMID.

If you have any questions about any of the changes implemented in this release, please contact us
