Plastics are widely used in daily life due to their versatility, affordability, and ease of processing. Their extensive applications make it crucial to understand how they respond to mechanical stress, especially in structural or load-bearing contexts. This study investigates the behavior of ABS (Acrylonitrile Butadiene Styrene), a commonly used thermoplastic, under uniaxial tensile loading conditions. The objective is to assess how mechanical stress and accumulated damage influence its performance and durability.

Recent developments in fracture mechanics are applied to polymer structures, with a focus on accurate design and dimensioning to ensure long-term structural reliability. A detailed understanding of how polymers deform, yield, and fail under various loads—particularly in the presence of micro-defects—is essential for predicting their service life and identifying critical failure thresholds.

The research utilizes experimental tensile testing combined with analytical approaches such as non-linear regression and damage modeling. These methods enable precise characterization of the material's mechanical properties and identification of key indicators of degradation. By capturing the evolution of damage during loading, the study provides insight into the points at which maintenance or replacement becomes necessary.

The results contribute to improved design strategies for polymer-based components, ensuring safer and more efficient use in engineering applications; the findings also offer a foundation for future research into the development of more resilient polymer composites tailored for high-stress environments.
