Mixed mode fracture testing should provide a more comprehensive knowledge of concrete in the softening range, which is needed for a complete modelling in finite element codes. After a survey of some mixed mode testing methods which have been applied so far it is shown that all of these are not capable to supply necessary data in a physically clear and independent way. This is the reason why a new equipment has been designed and built which uses plane quadratic push-off type specimens. Loading is controlled in two independent directions by displacement control. The main features of the equipment are described and the results of a few preliminary tests are presented. It is concluded that the equipment fulfills the requirements of stable testing. Further experiments are announced.
