This STP contains the proceedings from the ASTM International Committee E8 on Fatigue and Fracture sponsored symposium Predictive Material Modeling: Combining Fundamental Physics Understanding, Computational Methods and Empirically Observed Behavior held in November, 2001.
Papers in this publication are organized under three headings – Ferritic Steels, Electronic Materials, and Computational Techniques. Specific topics covered in these papers include:
- sub-sized Charpy-V specimens
- damage fracture mechanics
- reactor pressure vessel (RPV) steel
- LSI devices
- Weibull stress
- multi-axial yield surfaces
- X-ray computed microtomography
- image-based modeling
- percolation analysis
- porous shape memory alloy
- pseudoelasticity
- brittle fracture
- Beremin model
- transition fracture toughness models
- Ritchie-Knott-Rice
- cleavage fracture
- equivalent CTOD
- Zerilli-Armstrong (ZA) constitutive model
- creep crack growth
Safe life extension depends on the availability of robust methodologies that accurately predict both the fundamental material behavior and the structural response under a wide range of load conditions. The papers in this STP provide useful information for engineers, researchers, and others interested in extending the design life of structures.
