Benchmark LE1

Elliptic Membrane

The following results are for a model of the LE1 benchmark test from National Agency for Finite Element Methods and Standards (U.K.), also known as NAFEMS(1). Reduced integration elements for ANSYS as well as published ABAQUS results are provided for comparison purposes.

Coarse mesh



Fine mesh



Results

* The ABAQUS results were published in the Abaqus Benchmarks Manual(2) and neither the model nor the results have been verified.

The ANSYS (v10.0), Tahoe (v2.1) and CalculiX (v1.5) results were obtained from the same geometry mesh and boundary conditions with analogous elements.

The target vertical component of stress at the lower inside corner is: 92.7 MPa.
