| Abstract Scope |
Porous materials exhibit a variety of attractive functional properties for aerospace applications such as low density and low thermal conductivity. It is necessary, though, that these porous materials be mechanically robust, as they experience high stresses and vibrational fatigue. Testing these materials under service conditions is prohibitively costly, incentivizing computational approaches. However, the inherent microstructural stochasticity requires extensive experimental validation and benchmarking to accurately model their behavior. This study aims to quantify the tensile properties and impact of previous damage (e.g. cracks, through holes) on the damage and fracture of FiberForm. Damage accumulation will be observed and quantified through the duration of the tests using digital image correlation (DIC) and correlated with optical and electron microscopy of tested samples to observe the underlying mechanisms. These results will provide broad experimental data to inform and benchmark modeling approaches to accurately predict and tailor the reliability of porous parts under service conditions. |
