ABSTRACT
Based on linear elastic fracture mechanic (LEFM), stress cycles non-contributing crack growth from stress range spectrum is truncated for fatigue assessment. Calibration which make fatigue life Nc representing total applied stress cycle to failure instead of stress cycle contributing crack growth is considered for realistic fatigue assessment. Effectiveness of truncation and calibration is identified through actual fatigue reliability assessment case using weigh in motion measurement data. The result shows importance of considering stress spectrum truncation and calibration for Nc simultaneously for realistic fatigue reliability assessment.
