Fine-grained high-strength concrete has already been tested extensively regarding its uniaxial strength. However, there is a lack of research on the multiaxial performance. In this contribution, some biaxial tests are investigated in order to compare

The efficient simulation of complex fracture processes is still a challenging task. In this contribution, an enriched phase-field method for the simulation of 2D fracture processes is presented. It has the potential to drastically reduce computationa

Material models for the thermoplastic material behaviour of a dual-phase steel on a microscopic and a macroscopic length scale are developed in a continuum mechanics framework. Since the microstructure of the material is composed of the two phases ma

In this contribution we present a gradient enhanced damage based method to simulate discrete crack propagation in 3D polycrystalline microstructures. Discrete cracks are represented using the eXtended finite element method. The crack propagation crit

This paper describes a mixed extended finite element (XFEM) formulation that can handle nearly incompressible material behaviour for fracture mechanics problems as well as for heterogeneous materials under small and finite elastic and elastoplastic d

International audience; A combined continuous-discontinuous approach to fracture is presented to model crack propagation under dynamic loading. A gradient-enhanced damage model is used to evaluate degradation of the material ahead of the crack. This
