- 1982, IUTAM Granular Mechanics, in Delft. As in 1924 at the first IUTAM

conference on applied mechanics, where the profession of geotechnical
engineering got a boost by finding roots in mathematics and physics, this
IUTAM conference on granular mechanics gave a strong impulse to the
profession by advanced numerical methods, allowing to further develop
complex geometries and complicated material behaviour.
