The results can be viewed also as mpg-movie. In a round-robin he asked for the prediction of internal strains of a wedge spitting test. Any information about the test conditions can be found on his WWW-page. We submitted our results on december 22, 1998. To give you an impression of the test we did another mpg-movie.
Ongoing research is focused on reinforced concrete shells.
Here we apply the aforementioned concrete model to a 7-parameter shell theory that was extensively investigated by B chter and Bischoff . This theory has been further developped by Braun towards a multi layer approach which is actually used in the simulations. Each shell layer allows for a fully three dimensional constitutive model. The reinforcement is taken into account as general nonlinear orthotropic material based on a plasticity fomrulation. A first example shows the computation of the well known experimental works by Bouma.
