Anisotropic damage multiaxial model : rupture control numerical procedure and application until failure of reinforced concrete structures under impacts
type: Dataset
description: The need to predict the mechanical behavior of reinforced concrete industrial structures and assess their level of damage in extreme conditions under the action of dynamic loads requires the use of numerical simulations and develop reliable and robust material models. In this thesis, the model of induced anisotropic damage using a tensor variable of order 2 is extended to the case of low-level confined loads using a new modular criterion written with stresses. Through the mechanism of visco-damage, the model treats the entire solicitation rate range considered for reinforced concrete structures. The cyclic behavior with reclosing of cracks is taken into account and the damage can reach 1 exactly in one or more directions due to a new rupture management. The calculation of a tie-beam showed that this procedure is necessary to plasticize steel and prevent widespread damage concrete. During the experimental part of the thesis, characterization tests for concrete and pullout tests were conducted in cooperation with the Civil Engineering Department at ENS Cachan, followed by impact tests on beams on the Orion drop tower of DYN CEA Saclay laboratory. With a pragmatic consideration of steel-concrete interface, the comparison of calculations and tests showed that it was necessary to have a model of steel-concrete connection to avoid excessive concrete damage in the vicinity of reinforcements, as well as to reduce computing time, improve the regularization method, and take into account permanent deformations.
