Abstract

Directional thrusters are designed to provide force for short time periods.

• New generation of thrusters could be made using a High Entropy Alloy (HEA).
• Predicting fatigue damage initiation for this kind of metallic structure subjected to
cyclic loads is important.
• Design for fatigue resistance relies on empirical with high financial costs.
• Unified Mechanics Theory (UMT) will be used to predict fatigue damage initiation
of a material system without having experimental fatigue data

KeywordsDirectional thrusters; High Entropy Alloy (HEA); fatigue damage
