Lattice Fracture Model for Concrete Fracture Revisited: Calibration and Validation

The lattice fracture model is a discrete model that can simulate the fracture process of cementitious materials. In this work, the Delft lattice fracture model is reviewed and utilized for fracture analysis. First, a systematic calibration procedure that relies on the combination of two uniaxial tensile tests is proposed to determine the input...

Concrete in dynamic tension: The fracture process

The fracture properties of concrete are rate dependent. In this thesis the results on tensile tests at static, moderate and high loading rate are presented. The results show the influence of the loading rate not only the tensile strength, but also on the fracture energy, stress-defromation relation and fracture parameters, like fracture lengths...
