Ultra-Low Cycle Fatigue Life Prediction Model—A Review

نویسندگان

چکیده

This article is a review of models for predicting ultra-low cycle fatigue life. In the article, life prediction are divided into three types: (1) microscopic ductile fracture based on cavity growth and merger; (2) porous plasticity; (3) continuum damage mechanics. Furthermore, provides critical assessment current state research models, highlighting limitations challenges faced by each model type. Ultimately, this aims to provide comprehensive overview different available guide future in important area materials science engineering.

Ultra-Low Cycle Fatigue Fracture Life of a Type of Buckling Restrained Brace

Buckling restrained braced frames (BRBFs) for seismic load resistance have been widely used in recent years. One of the key requirements for a buckling restrained brace is to sustain large plastic deformations under severe ground motions. The core of a buckling restrained brace is prone to fatigue fracture under cyclic loading. The earthquake induced fracture type of the core plate in a bucklin...

Energy-Based Prediction of Low-Cycle Fatigue Life of CK45 Steel and SS316 Stainless Steel

In this paper, low cycle fatigue life of CK45 steel and SS316 stainless steel under strain-controlled loading are experimentally investigated. In addition, the impact of mean strain and strain amplitude on the fatigue life and cyclic behavior of the materials are studied. Furthermore, it is attempted to predict fatigue life using energy and SWT damage parameters. The experimental results demons...

Ultra Low Cycle Fatigue of Axisymmetric Freestanding Nanoscale Gold Films

We present ultra low-cycle fatigue experiments of axisymmetric nano-crystalline gold films of nano-thickness deformed by a spherical indenter using a recently developed freestanding membrane test. Freestanding membranes of gold were centrally deflected using a spherical indenter attached to a MEMS load cell. Fabrication of the films for these experiments yielded films 100 nm thick and 500 μm in...

Multiaxial high-cycle fatigue criterion and life prediction for metals

A new high-cycle fatigue criterion based on the critical plane approach is proposed in this paper. Unlike most of the other multiaxial fatigue criteria based on the critical plane approach, the critical plane is directly correlated with the fatigue fracture plane. The proposed criterion has a wide range of applicability from very ductile metals to extremely brittle metals. Mean stress effect is...

A Novel Viscosity-Based Model for Low Cycle Fatigue Creep Life Prediction of High-Temperature Structures

Damage evolution during low cycle fatigue, creep, and their interaction behavior is actually a ductility exhaustion process in response to cyclic and static creep. In this article, a novel viscosity-based model for low cycle fatigue creep life prediction is presented in an attempt to condition viscosity-based approaches for general use in isothermal and thermo-mechanical loading. In this model,...
