RISModeling the Temperature Dependence of Tertiary Creep Damage of a Ni-Based Alloy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To capture the mechanical response of Ni-based materials, creep deformation and rupture experiments are typically performed. Long term tests, mimicking service conditions at 10,000 h or more, are ...
Constitutive Modeling of Multistage Creep Damage in Isotropic and Transversely Isotropic Alloys With Elastic Damage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the pressure vessel and piping and power industries, creep deformation has continued to be an important design consideration. Directionally solidified components have become commonplace. Creep ...
Characterization of the Creep Deformation and Rupture Behavior of DS GTD-111 Using the Kachanov–Rabotnov Constitutive Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Creep deformation and rupture experiments are conducted on samples of the Ni-base superalloy directionally solidified GTD-111 tested at temperatures between 649°C and 982°C and two ...
An Improved Anisotropic Tertiary Creep Damage Formulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Directionally solidified (DS) Ni-base superalloys are commonly used as gas turbine materials to primarily extend the operational lives of components under high load and temperature. The nature ...
