Despite their lightweight and superior performance in service, damage in structural composites involves extremely complicated nonlinear processes acting from the micro-scale to the structural scale. Therefore, high fidelity numerical methods and computer simulation have been extensively used to predict fracture and damage process in composite structures. A multi-scale analysis toolbox for composite materials is developed targeting discrete damage evolution in composite materials. The software toolkit as a virtual multi-scale laboratory (a) eases the burden of experiments, (b) provides the evolution of three-dimensional crack paths in composite material and (c) predicts the failure and damages in fiber reinforced composite materials.
SeaPort-e approved company has developed an innovative approach and a coupled sensing tool to perform analysis and prediction of environmentally assisted damage accumulation in structural components. Ensuring the safety and future condition of aircraft requires the analysis of damage accumulation at critical locations due to both applied stresses and local environmental conditions; prognostics models that can take into account variation of loading and environmental conditions for calculation of components’ remaining life are needed. The analysis tools developed implement unique analytical formulations linking environmental damage and mechanical damage to perform life calculation at a component level for different environmental conditions. This engineering and software design company seeks Primes interested in identifying platforms that need innovative solutions for corrosion assisted damage accumulation and cracking.
