What is it about?
It was decided that the purpose of this paper was to determine the intersection of fatigue characteristics for smooth and notched specimens and to present a high-cycle life model for aluminium alloys including AA2519 T62 alloy.

Why is it important?
The issue of fatigue life is inextricably linked to the design process of technical objects. The aforementioned life represents a kind of compromise between commercial profit and product features that are determined by the user, including the maximum lifetime of the object. Durability issues take on great importance when they have to do with safety, especially when operating objects moving at high speeds, such as airborne vessels, or objects whose damage will occur at a considerable distance from a facility that can provide assistance, as is sometimes the case during deep-sea shipping voyages.
Perspectives
Future research on composite materials used in vehicle bodywork should focus on improving their long-term durability, repairability, and damage assessment methods. Developing standardized testing protocols for low-energy impacts and optimizing fiber orientation can enhance performance and safety. There is also potential for integrating smart sensors into composite panels to enable real-time structural health monitoring. These advancements could lead to lighter, more efficient vehicles with lower repair costs and improved sustainability.
