7. Validation Test Case¶
ACCS has been validated against data published in the literature [1]. This test case looks at the spring-in angle of 270° of 50 mm diameter tubes. They were made of Hexcel AS4/8552 unidirectional plies in cross-ply lay-up with thicknesses ranging between 1 mm and 4 mm. The figure below presents the comparison between the results obtained with ACCS and previously published.

7.1. ACCS RTM Solver Test cases¶
ACCS RTM Solver has been validated against multiple test cases. Darcy’s law is used to predict the theorical infusion time for each example model. The solver’s output is then compared to this prediction.
