MECHANICAL RESPONSE OF PA6 UNDER ENVIRONMENTAL CONDITIONS: A DUAL APPROACH USING EXPERIMENTS AND NUMERICAL ANALYSES

Polyamide 6 (PA6), also known as Nylon 6, is a thermoplastic material that belongs to the nylon polymer class. Its structure includes repeating amid groups (-CONH-) within the molecular chain. Due to its semicrystalline configuration, this polymer is characterized by outstanding mechanical properties, such as high tensile strength and a significant ability to resist impact. This paper focuses on the impact of environmental factors on the mechanical and elastic characteristics of PA6, with the main objective of identifying how various external factors influence the mechanical and elastic characteristics of this material used in various industrial applications, all of which is intended to support future investigations on the behavior of these types of materials in different other working environments. However, the interaction of these materials with various environmental factors leads to structural and functional changes that can compromise or, in some cases, improve their performance. Recent studies in the field of materials science and mechanical engineering are based on the impact of environmental factors such as temperature, humidity, ultraviolet radiation, and exposure to various chemicals on the mechanical and elastic properties of polymers.
