Elastoplastic modeling of fatigue cracks

open access: yesOmsk Scientific Bulletin
The presented work provides a detailed analysis of modern approaches to creating elastoplastic models of surface crack growth that take into account the influence of the type of biaxial loading on the development of stresses and strains at the crack tip and, accordingly, on the crack growth rate.

Piezoresistive Monitoring of Carbon Nanomaterial‐Reinforced Epoxy Composites Under Cyclic and Fatigue Loading: A Review

open access: yesAdvanced Engineering Materials, EarlyView.
Carbon nanomaterial‐reinforced epoxy composites exhibit pronounced piezoresistive behavior, enabling intrinsic damage sensing under cyclic and fatigue loading. This review critically compares carbon nanotube and graphene systems, correlating filler content, percolation threshold, and gauge factor with sensing stability and damage evolution.

Using low-cycle fatigue method to predict fatigue life of rail crack initiation location by means of 3D-finite element simulation on sharped curved track [PDF]

open access: yesInternational Journal of Railway Research, 2023
Dynamic modeling of wheel-rail interaction is significant for accurate fatigue analysis of railways. Both the location and magnitude of wheel-rail stress must be evaluated accurately and efficiently via computational tools.

3D‐Printed Giant Magnetoresistive (GMR) Sensors Based on Self Compliant Springs

open access: yesAdvanced Engineering Materials, EarlyView.
This work explores 3D‐printed GMR sensors utilizing self‐compliant spring structures and conductive PLA composites. By optimizing arm width, we achieved high piezoresistive (0.34%/mm) and magnetoresistive (0.77%/mT) sensitivities. Demonstrated through Bluetooth‐integrated pressure and magnetic position sensing, these full printed low‐cost, customizable

Time and Crack Length Dependent Stochastic Models of Fatigue Crack Growth. State-of-the-Art Review

open access: yesEngineering Transactions, 1992
Random character of fatigue crack growth observed in experiments inspires many researchers to apply the methods of probability theory and theory of stochastic processes in modeling of the phenomenon. Among many proposals the continuous stochastic models

Life-cycle of fatigue sensitive structures under uncertainty [PDF]

open access: yes, 2013
Fatigue is the one of the main contributors to problems related to structural safety of civil and marine structures. Life-cycle management (LCM) techniques considering various uncertainties can be used to predict the safe service life of fatigue ...

Stochastic modeling of fatigue crack propagation [PDF]

open access: yesProceedings of the 1997 American Control Conference (Cat. No.97CH36041), 1997
This paper presents a stochastic model of fatigue-induced crack propagation in metallic materials. The crack growth rate predicted by the model is guaranteed to be non-negative. The model structure is built upon the underlying principle of Karhunen-Loeve expansion and does not require solutions of stochastic differential equations in either Wiener ...
