RISMachine Learning Models for Creep Rupture Prediction of Inconel 617
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Creep rupture data are not always available at the desired temperature or stress levels, and performing creep tests can be both time-consuming and expensive. Creep rupture data from various sources are often combined for ...
The Stress-Sensitivity, Mesh-Dependence, and Convergence of Continuum Damage Mechanics Models for Creep
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The classic Kachanov–Rabotnov (KR) creep damage model is a popular model for the design against failure due to creep deformation. However, the KR model is a local approach that can exhibit numerically unstable damage with ...
Finite Element Analysis of Waspaloy Using Sinh Creep Damage Constitutive Model Under Triaxial Stress State
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The creep deformation and damage evolution of nickel base superalloy (Waspaloy) at 700 آ°C are studied using the classic Kachanov–Rabotnov (KR) and a recently developed Sinhyperbolic (Sinh) model. Uniaxial creep ...
Metamodeling Time-Temperature Creep Parameters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: There exist many time-temperature parameter (TTP) models for creep rupture prediction of components including the Larson–Miller (LM), Manson–Haferd (MH), Manson–Brown (MB), Orr–Sherby–Dorn (OSD), Manson–Succop (MS), ...
An Advanced Sine-Hyperbolic Creep-Damage Model Incorporating Threshold Strength
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study aims at improving the classic sine-hyperbolic (Sinh) creep-damage model to predict minimum-creep-strain-rate (MCSR), rupture, damage, and creep deformation. The Sinh model employs a continuum-damage-mechanics-based ...
