A Probabilistic Treatment of Microstructural Effects on Fatigue Crack Growth of Large Cracks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A probabilistic model has been developed for treating the effects of microstructural variation on the fatigue crack growth response of large cracks in structural alloys. The proposed methodology ...
Inelastic Deformation Under Nonisothermal Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of this paper is to evaluate, both experimentally and analytically, the appropriate forms of the hardening evolution equations in unified constitutive models for conditions involving ...
Viscoplastic Characterization of A533B Steel at High Strain Rates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The yield strength of A533 grade B class 1 steel is relatively low. Dynamic fracture in test specimens and pressure vessels made with this material is generally accompanied by significant ...
A Probabilistic Micromechanical Code for Predicting Fatigue Life Variability: Model Development and Application
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper summarizes the development of a probabilistic micromechanical code for treating fatigue life variability resulting from material variations. Dubbed MICROFAVA (micromechanical fatigue ...
Effect of Time and Temperature on Thermal Barrier Coating Failure Mode Under Oxidizing Environment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thermal barrier coatings (TBCs) have been recently introduced to hot section components, such as transition pieces and the first two stages of turbine blades and vanes of advanced F, G, and ...
A Comparison of Crack-Tip Field Parameters for Large and Small Fatigue Cracks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A comparison of the elastic-plastic crack-tip fields of large and small fatigue cracks has been made using the ΔJ-integral approach. Using experimental strain and displacement range measurements ...
Biaxial Strength of HY 80 Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The biaxial deformation behavior of HY 80 steel has been examined by testing thin wall tubes under combined axial tension and internal pressure. The effective stress-strain curves and the ...
Phenomenological Modeling of Hardening and Thermal Recovery in Metals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modeling of hardening and thermal recovery in metals is considered within the context of unified elastic-viscoplastic theories. Specifically, the choices of internal variables and hardening measures, ...
Model for the Effect of Fiber Bridging on the Fracture Resistance of Reinforced-Carbon-Carbon
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A micromechanical methodology has been developed for analyzing fiber bridging and resistance-curve behavior in reinforced-carbon-carbon (RCC) panels with a 3D composite architecture and a SiC surface ...
Analysis of Corrosion Fatigue Crack Growth in Welded Tubular Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An improved fracture mechanics model for fatigue crack growth in welded tubular joints is developed. Primary improvements include the use of a wide-ranged equation for the fatigue crack growth ...
