Effective Elastic Moduli of Short-Fiber Composite with Sliding Contact Conditions at Interfaces

The article delves into the critical factors influencing the mechanical properties of matrix-based composites, focusing on the role of interface surfaces and contact conditions. It introduces a combined approach of homogenization and boundary element methods to analyze the effective elastic moduli of short-fiber composites with sliding contact at interfaces. This innovative methodology accounts for the complex three-dimensional structures and imperfect contact conditions, providing a detailed understanding of the composite's elastic macrocharacteristics. The study presents numerical results and discussions, highlighting the impact of sliding interfacial contact on the effective elastic properties of composites, both for ordered and randomly oriented short fibers. The findings offer valuable insights into the behavior of composites under various conditions, contributing to the design and durability assessment of composite structural members.
