(GRS-615) Project BIGBEN - Constitutive Equations for Sodium and Calcium Bentonites

K.-P. Kröhn, M. Kröhn

Funding of experimental as well as theoretical work in the framework of project BIGBEN (FKZ 02 E 11284) by the German Federal Ministry for Economic Affairs and Energy (BMWi) is gratefully acknowledged.

Highly valuable was the help of Juan Vertelman (atum3D) and Ben Illesch (KEYANCE Deutschland GmbH) with respect to the measurements concerning the accuracy of 3D-printed materials. They provided generously test prints that expanded the range of ma-terials and of tested printing techniques considerably. Also, the open scientific exchange about 3D-printing for hydraulic tests with Patrick Bruines and Martin Stigsson (both SKB) is much appreciated.
