Abstract

This investigation utilizes the open hole tension (OHT) specimen loaded in tension-tension fatigue under isothermal, fixed frequency conditions. A range of load levels and temperature levels where chosen to assess performance. These loads and temperatures ranged from relatively benign conditions (low stress, room temperature) up through aggressive conditions (high stress, high temperature). Measurements of stiffness, damage accumulation, residual strength, weight loss, and glass transition temperature (Tg) were made. Results from this work will help explain the roles of aging, load and fatigue in the performance of elevated temperature OHT specimens as well as provide insights to the individual and synergistic contributions of each process.
