| During his leave of absence from the University of Colorado at the Politecnico of Milano, Prof. Saouma performed tests on large jointed concrete specimens subjected to reverse cyclic loading. | |
| Tests were performed by Mr. Eric Puntel as part of his PhD thesis in the Structural Engineering Laboratory of Politecnico. | |
| Computational Enthusiasts are invited/challenged to provide a numerical prediction for those tests. | |
| Results will be compiled and presented at a forthcoming international event. |
