First guest blog posting... Benchmarking Composites in Abaqus from Matthew Knight

Posted by Laurence Marks

When I started blogging the plan was that I'd get other people to contribute, thereby lightening the load on me. Like most great plans this hasn't actually turned into reality, until now... So thanks to Matthew Knight of Simulia UK who put together this piece on benchmarking composites.


There is a wealth of information and resources available to Abaqus users; however in many case this is not always being utilized to its greatest effect. For any user the starting point should be the Abaqus documentation, which includes an Analysis Users Manual, Example Problems Manual, and Benchmark Manual. There is also the Knowledge Base which can be accessed through which includes useful information and answers. Finally there is the Simulia Learning Community ( where you can read and post iQuestions.

In addition to these various sources, NAFEMS provide technical resources such as publications and technical benchmarks. NAFEMS is an independent not-for-profit association focusing on the practical application of numerical engineering simulation techniques such as the Finite Element Method for Structural Analysis, Computational Fluid Dynamics, and Multibody Simulation.

To verify the basic composites capability within Abaqus a simple model was constructed based on a test case within the NAFEMS Composite Benchmark handbook. As expected, Abaqus accurately predicts the deflection, bending stress and interlaminar stresses within the composite. Plots below show the simulated deflection against the NAFEMS target solution.
