FS-Fracture undertakes fracture and fatigue assessments applicable to a wide range of applications using industry recommended or industry accepted principles and techniques.
Stress Intensity KI evaluated using QPE's in FS2000
FS-Fracture performs basic defect assessments based on the requirements of BS 7910:2005 "Guidance methods for assessing the acceptability of flaws in metallic structures".
-
Simple Operation - All input data is input using analysis specific forms each with easily recognisable parameters.
-
Fracture - (Level 1A, 2A, 2B, 3A & 3B) assessments for surface, embedded and through thickness flaws.
-
Fatigue - Crack growth fatigue predictions for surface, embedded and through thickness flaws using the recommended fracture mechanics principles of BS7910:2005.
Stress Histories
Stress histories are read from user defined text files using various
formats.
Spectral Methods (SeaState)
Fatigue damage from PDFs
(Jonswop etc.) processed in conjunction with user defined transfer
function (RAOs)
Raw Data Processing
Stress histories can also be produced by processing raw
stress/strain data.
- Peak/valley identification
- ‘Rainflow ‘ closed strain cycle counting
- Stress histograms produced
- Mean information in triangular format
Interfaces with FS2000 post-processors
Interprets the stress range output from FS-OffFat and the standard
stress range extraction module of FS2000
