Abstract

A new experimental setup for concrete mixed-mode crack propagation is presented. The specimen and loading correspond to a Nooru-mohamed test, i.e. a square double-notched specimen submitted to in-plane tension and shear. Innovation comes from the loading setup: a hexapod ma- chine whose 3D motions are controlled by a Digital Images Correlation algorithms using several cameras“live” recordings. The interest of this setup is that the 3D (in-plane and out-of-plane) bound- ary conditions will be controlled contrary to the original Nooru-Mohamed setup, which conditions have a tremendous influence on the crack propagation, and thus further confrontations to numerical simulations.
