COURSE OBJECTIVE
This course will show that the basic principles of fatigue life estimation are relatively straightforward and certainly within the role of typical stress, dynamics and FEA design engineers. The course will focus on both time domain and frequency domain fatigue and will bring together structural dynamics, FEA and fatigue analysis in order to show how systems with dynamic (resonant) response can be assessed for fatigue life. The style of the course will be to present the basic techniques required to perform FEA based fatigue life calculations in such a way that even engineers with no prior knowledge of fatigue life estimation methods can confidently apply the techniques. Throughout the course relevant examples will be used as a means of demonstrating the theoretical methods.
