AA&S 2019 Training – How Do You Verify the Accuracy of Engineering Simulations?
Abstract: This 2-hour training course will review strategies for verifying the accuracy of engineering simulation data, including best practices and common pitfalls engineers may encounter when assessing the quality of their engineering simulation results. The course will focus on the four key quality of solution checks that should be performed to confirm solution verification of detailed stress results. We will examine a variety of publicly-available and industry-applicable case studies, benchmarks and industry examples, to determine the most efficient and reliable methodologies to perform solution verification.
Originally presented as a training course at the 2019 AA&S/PS&S conference in Washington, D.C.

“A screening of existent commercial and non-commercial tools was carried out in respect to their fracture mechanics capabilities, their design abilities, implementation as well as their complexity. Although, there are many software possibilities, only those within the reach of the author were evaluated. This resulted in the selection of the commercial tool StressCheck®. The assessment of crack propagation on compact tension and two stringer specimens governed by the Paris and Forman regimes was satisfactory compared with experimental results using the material data from simple standard specimens.”
