The Math of Random Signals, Fatigue Damage, Vibration Tests

Description

Ready to Learn About the Fascinating World of Fatigue Damage and Its Application in Engineering ?

1: Introduction

Are you interested in learning about fatigue damage and its application in engineering? If so, enroll in this comprehensive course and delve deep into the mathematics of fatigue damage, from the derivation of essential equations to the application of the theory in real-life situations.

2: Course Objectives

This course is designed for anyone interested in vibration tests and reliability engineering, as well as those who want to see the beauty of mathematics applied to engineering. You will learn about stochastic processes, probability distributions, and their role in real-life applications, as well as single-degree-of-freedom systems, the probability density of the maxima of a random process, and much more.

3: Instructor Expertise

The concepts in this course are based on the instructor's PhD dissertation: “Advanced Mission Synthesis Algorithms for Vibration-based Accelerated Life-testing,” which has been publicly available since February 2023 after a two-year "embargo", because the algorithms contained therein, could not be disclosed.

You will also have access to Graphical User Interfaces (GUI) developed by the instructor in collaboration with companies interested in the PhD project to see how equations can be implemented to generate vibratory signals.

4: Course Structure

This course will introduce you to fatigue-life estimation tests that aim to reproduce the entire fatigue damage experienced by the component during its operational life, but in a shorter amount of time. You will learn about how to tailor these tests to specific applications and generate signals that have the same "damage potential" as the environmental conditions to which the components are subjected.

5: Benefits of the Course

By enrolling in this course, you will gain advanced mathematical concepts that are intuitive to understand, and the connection to real-life applications will always be highlighted. You will learn how to relate a Power Spectral Density (PSD) to the fatigue damage, which is essential for creating signals to be used during tests. Additionally, you will learn about non-Gaussian signals, which are important since there are signals measured in real-life applications that show a deviation from the Gaussian distribution due to the presence of peaks and bursts in the signals.

6: Course Content

The course content includes:

- Introduction to fatigue damage

- Stochastic processes and probability distributions

- Single-degree-of-freedom systems

- Probability density of the maxima of a random process

- Tailoring fatigue-life estimation tests to specific applications

- Generating signals with the same "damage potential" as environmental conditions

- Relating Power Spectral Density (PSD) to fatigue damage

- Creating Gaussian and non-Gaussian signals

7: Course Delivery

This course is available online and can be accessed at any time, from anywhere in the world. You will have access to instructional videos, but also reading materials (my PhD dissertation), to deepen your understanding if necessary.

8: Course Duration

The course duration is flexible and self-paced, allowing you to learn at your own pace. It is estimated that the course will take around 10-12 hours to complete ( even though it lasts less, but you need time to think !!! :) )

9: Course Completion

Upon completion of this course, you will receive a certificate of completion, which can be used to demonstrate your knowledge and skills in the field of fatigue damage and its application in vibration testing.
