5 Zoom Meetings for those interested to join FABER Action

FABER networking project is funded for next four years by the COST Association. Its goal is to solve the current deadlock in validating the metal fatigue life evaluation methods and solvers by establishing benchmark sets of curated experimental fatigue data, with the focus set on the high-cycle fatigue category above all.

FABER (Fatigue Benchmark Repository) to be funded by COST. Join us!

A dream came true, and the fifth submission of this networking project to COST Association was approved for funding.

 

It will start from November 2024 for the total duration of 4 years. The broad cooperation will focus on developing tools and data sets, which can streamline research and validation of fatigue estimation criteria.

Workshop on Computational Fatigue Analysis 2023 – FKM-Guideline Non-Linear

From October 30 to November 1, 2023, we hold 11th Workshop on Computational Fatigue Analysis in Prague, Czechia. This time, we chose the attractive topic of the latest extension of the FKM-Guideline for Analytical Strength Assessment. This guideline developed for years by FKM Association in Germany provides clear description how to deal with static and fatigue analysis of industrial components.

Lecture by P. Yadegari on “Fatigue strength of ultra-high strength steels and surface-hardened components”

Lecture by Patrick Yadegari on “Fatigue strength of ultra-high strength steels and surface-hardened components” will be held on-line on Tuesday September 5 at 3PM CET. Its approximate duration is expected 1 hour, but it will depend on the scope of the discussion and the questions of participants. If you wish to take part, please write me to papuga@pragtic.com, so that I could send you the access link to the Zoom platform. Here is the abstract to the lecture:

1st Workshop on Thermodynamics of Fatigue Process

The workshop takes place on-line only on June 14 from 2 PM CET. It is intended to serve as a networking event, where interested researchers present their focused domain. The subsequent brainstorming will help us to evaluate whether there is a will for a broader cooperation among the participants, and if to transform this workshop into something more regular.

If you do not feel strong enough to present, you are still invited to join us - simply let me know to my e-mail address to get the access to the workshop. No fee requested.

PhD position in france : modelling of fatigue crack propagation in metallic materials weakened by hydrogen

Dear all

Please fin attached a PhD proposal for the beginning of the 2023 academic year, proposed by the Institut P' (Poitiers, France) in collaboration with the LSPM lab (University Sorbonne Paris Nord), aiming at modelling fatigue crack propagations in metallic materials under gazeous hydrogen environnement.

Predicting high cycle and ultrasonic vibration fatigue with unified mechanics theory

The unified mechanics theory (UMT) is ab-initio unification of the second law of thermodynamics and Newton's universal laws of motion, in which Boltzmann's second law of entropy formulation governs dissipation & degradation. Hence, the unified mechanics theory does not require any empirical dissipation & degradation potential function or an empirical void evolution function. Material degradation is quantified on the Thermodynamic state index (TSI) axis based on the specific entropy production, which starts at zero and asymptotically approaches one at failure.

Modeling fatigue of pre-corroded metals with unified mechanics theory

The unified mechanics theory (UMT) was used to develop a model to predict the fatigue life of pre-corroded steel samples with BCC structure. Details of the experimental validation are also provided.

Defect-based Physics-Informed Machine Learning Framework for Fatigue Prediction

I would like to draw your attention to our recently proposed predictive method based on a semi-empirical model (LEFM) and Neural Network, exploiting the Physics-informed Machine Learning concept. We show how the accuracy of state-of-the-art fatigue predictive models, based on defects present in materials, can be significantly boosted by accounting for additional morphological features via Physics-Informed Machine Learning.

Fatigue of Graphene

Materials can suffer mechanical fatigue when subjected to cyclic loading at stress levels much lower than the ultimate tensile strength, and understanding this behaviour is critical to evaluating long-term dynamic reliability. The fatigue life and damage mechanisms of two-dimensional (2D) materials, of interest for mechanical and electronic applications, are currently unknown. Here, we present a fatigue study of freestanding 2D materials, specifically graphene and graphene oxide (GO).

Analytical Models for Fatigue Life Prediction of Metals in the Stress-Life Approach -- phd thesis by Pietro D’Antuono

dear collegues

  I'd be very grateful if you could have a look, if not a deep reading, at the phd thesis of my last student, playing on classical results on uniaxial fatigue, but with a view of simple, unified perspective on constant and varying amplitude fatigue.  We made large use of e-fatigue.com web site and the data in there.
 Thanks in advance for any remark.  The final thesis will be submitted in few weeks time.
