Abstract

Journal of Reinforced Plastics and Composites, Volume 45, Issue 7-8, Page 1987-1993, April 2026.
Based on the different failure modes of fiber-reinforced composites (FRP) under random vibration fatigue loading, these materials are categorized into brittle and ductile types. The study summarizes the damage evolution patterns of these two types of ...
