Multiaxial Concrete Material Behavior
Continuum mechanics provides a framework to describe the behavior of solids. Two scales are considered to describe structural concrete with continuum mechanics: mesoscale and macroscale. Isotropy is strongly connected with various aspects of directions namely action direction, reaction direction and material direction. Regarding the uniaxial case nonlinear material behavior of concrete is characterized by a decreasing tangential material stiffness. A change of plastic strains or plastic flow occurs in the case of yielding. Yielding is ruled by a yield function. Elastoplasticity is characterized through the evolution of permanent strains with a constant nominal material stiffness. Crack formation is a characteristic property of plain and reinforced concrete structures. Cracks are unavoidable due to the relatively low tensile strength of concrete. The microplace concept represents microscopic boundary layers by a variety of microscopic planes.
