ALTISS Technologies provides fatigue and fracture evaluations required for R&D, Fitness-For-Service, Forensic, Service Life Prediction and Third-Party Verification analyses.

With proper fatigue assessment, the operational life of the component and its potential mode of failure can be accurately predicted. ALTISS Technologies’ engineers use fracture mechanics and fatigue analysis to assess the fatigue life of components and assemblies under various loading and service conditions.

ALTISS Engineers will:
  • Conduct FEM analysis for all loading cases of concern 
  • Identify possible crack locations based on stress concentrations and failure criteria
  • Evaluate flaw size based on NDA capabilities and appropriate Engineering Code recommendations
  • Identify crack mode
  • Select an appropriate crack type from an appropriate Engineering Code
  • Conduct fatigue analysis to estimate service life
  • Provide recommendations such as to alter, repair, monitor, retire or replace the equipment

ALTISS' Fatigue and Fracture Expertise is in:
  • Fatigue and fracture analysis of HPHT equipment
  • Application of API 579-1/ASME FFS-1 2007 Fitness-For-Service 
  • Application of ASME 2010  BOILER AND PRESSURE VESSEL CODE, Section VIII Division 3
  • Application of FAD diagrams to the evaluation of crack-like flaws in components
  • Advanced use of ABAQUS®
  • Application of XFEM methodology for fracture analysis
  • Development of specialized MatLab® fatigue analyses codes
