RISAssessment of the Wilshire-Cano-Stewart Model Using Strain Energy Density Dissipation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, strain energy density (SED) is employed as a creep damage parameter to calibrate the Wilshire-Cano-Stewart (WCS) model. The WCS model is an adaptation of the Wilshire equations combined with continuum damage ...
Creep Lifetime Prediction of Alloy 617 Using Black Box Machine Learning Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study explored the application of black box machine learning (ML) to build high throughput models that predict the creep response of Ni-based Alloy 617. Black box ML refers to highly complex machine learning algorithms ...
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 ...
An Extrema Approach to Probabilistic Creep Modeling in Finite Element Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper introduces a computationally efficient extrema approach for the probabilistic predictions of creep in finite element analysis (FEA). Component-level probabilistic simulations are needed to assess the reliability ...
