Common Mistakes made in Fatigue Analysis

Fatigue life prediction is a common task for engineers. How do we make sure that we are doing the right thing? There are many codes and FE tools available for metal fatigue analysis. Are those tools doing it right?
We have compiled an ebook with an overview of common mistakes made in metal fatigue analysis.

Consultancy

Fatigue Consultancy
We offer consultancy & fatigue analysis, failure analysis, tools development and research & development, all in the field of metal fatigue. Thanks to the large experience with fatigue of lightweight structures, gained in the aerospace industry and in university research, Fatec Engineering has the capability to give valuable advice and support in this field.


Courses & Training

Fatigue Courses
Managing and preventing problems due to metal fatigue should be considered as a key capability of a structural engineer. We can help you getting the required knowledge by offering courses and training.

In-Company Courses

Fatigue In-Company Courses
We also offer the possibility of customized courses, i.e. customized selection of topics and/or customized mixture of class training and webinars. After all, the course that fits your daily needs will be the most appropriate for you. With a customized in-company course you can select the topics that meet your requirements the best.

  • What is Fatigue?

    Metal fatigue is about the predominant cause of failure of structures. But what is fatigue? Fatigue occurs when a structure is subjected to cyclic loading. If the stress amplitude exceeds Continue Reading →

  • Description of a S-N Curve

    Fatigue properties of materials are often described using the fatigue limit or the S-N curve (fatigue curve, Wöhler curve). The S-N curve describes the relation between cyclic stress amplitude and Continue Reading →

  • Fatigue Analysis using Local Stresses

    The common approach for fatigue life analysis is using S-N curves based on nominal stresses (i.e. average stresses in the net section). Depending on the severity of the stress concentration Continue Reading →

Guidelines for Fatigue Life Analysis

Guidelines for Fatigue Life Analysis

In this book, guidelines are given for fatigue life estimations and analysis. A known quote from Arthur Schopenhauer is: “Wo das Rechnen anfängt, hört das Wissen auf”. One may translate this to: “Where calculating starts, understanding ends”.
The objective of this book is to give the reader background information and knowledge on fatigue analysis methods (i.e. understanding the calculation). It is therefore neither a text book nor a recipe book, but the missing link in-between.
