Evaluation of Nonlocal Approaches for Modelling Fracture in Notched Concrete Specimens
Original language description
In concrete, growth and coalescence of microcracks lead to formation of visible fracture process zones that transfer stresses by crack bridging and aggregate interlock. Commonly, the behaviour of the fracture process zones is modelled by nonlinear fracture mechanics approaches using stress-strain laws with strain softening. One group of nonlinear fracture mechanics approaches suitable for computational structural analysis are nonlocal models, which lead to regular strain distributions over the fractureprocess zones, independently of the size of finite elements. This is achieved by evaluating the stress at each point based on weighted averages of state variables in the vicinity of that point. However, there is no consensus how the influence of boundaries should be taken into account by the averaging procedures. In the present comparative study, nonlocal damage models with different averaging methods and constitutive laws are investigated, with attention focused on the influence of boun
