Post‐installed anchors are used to connect structural and non‐structural members in a wide range of applications in concrete structures. A specific category of post-installed anchors includes the bonded fasteners (BF) and the bonded expansion fasteners (BEF). These systems comprise a steel anchor, threaded rod or a rod with conical expansions, as well as a thermoset polymer which serves as the adhesive between the substrate material, typically concrete and the steel part of the fastener. Both systems are used for heavy load applications and/or applications in cracked concrete under dynamic loads. The product development of these systems requires the characterization of several different parameters from the material level of each component to that of the fastening system. On the other hand, a product development phase usually involves a trial and error procedure which could increase the development time and costs. The product development phase can be shortened by the utilization of numerical simulations of different prototypes. However, such a task is not always straightforward, since the aforementioned fastening systems involve complex materials and complex interactions under different loading conditions, e.g. cracked concrete, sustained load, dynamic loads, or temperature effects. This contribution presents an overview of a powerful numerical approach that utilizes sophisticated models and it is able to link the material properties to the system response allowing the acceleration of the development of the final system. In particular, this study utilizes the Lattice Discrete Particle Model [1] for concrete and Grassl-Jirasek Model [2] for the adhesive mortar demonstrating its ability to accurately predict the static, dynamic and time-dependent performance of different anchor systems.
