Analysis of mechanical behavior of fiber-glass plastic with hole pattern using digital image correlation and acoustic emission methods.

This article discusses the analysis of the mechanical behavior of fiber-glass plastic with a hole pattern using digital image correlation and acoustic emission methods. The study focuses on deformation processes, damage accumulation, and fracture in polymer composites in stress concentration zones. The researchers conducted mechanical tensile tests on fiber-glass plastic specimens with different hole patterns and analyzed the displacement and strain fields using a non-contact optical video system. The results showed that the bearing capacity of the material decreased for certain hole patterns, and the fracture patterns varied depending on the hole arrangement. The document also includes references related to the influence of internal technological defects on the mechanical properties of structural CFRP and the AISC specification for structural steel buildings.
