Recent studies have made an attempt to couple computational structural dynamic tools with sophisticated computational fluid dynamic (CFD) solvers. The CFD approach is still at a nascent stage and discrepancies can be observed in both phase and amplitude of the predicted load. Due to the… More

For the Phase I effort, Global Engineering and Research Technologies (GERT) will develop a validated analysis tool to predict damage initiation and growth as well as residual strength composite multiple-lap joints with many staggered bolts. The analysis tool will be based on the merger of (local)… More

For the Phase I effort, a team comprised of experts in the areas of alternative high performance computing architectures such as the GPU, IBM Cell BE and Field Programmable Gate Arrays (Research Institution), and finite element analysis and continuum mechanics (Global Engineering Research and… More

For the Phase I effort, Global Engineering and Research Technologies (GERT) will develop a validated methodology to predict damage initiation and growth or durability of composite materials under cyclic loading in extreme temperature conditions. This effort will demonstrate the feasibility of the… More

Based on the foregoing, the goal of this proposed project is to develop a novel methodology based on the peridynamic (PD) theory to predict fatigue life of aerospace structures with high fidelity. A new fatigue model will be implemented in PD framework. The model and its implementation in PD will be… More

During a components service life, damage due to high or low energy impact may be introduced, which may lead to premature failure of these structures. Component level structural testing and analysis of advanced composites is prohibitively expensive and time consuming. Instead, using robust and… More

The Phase I effort will establish the validity, merit and feasibility of the proposed project to address bonded joint configurations under general mechanical and thermal loading while including the presence of process dependent critical material properties such as fracture toughness for the adhesive… More
