Peridynamics for the analysis and optimisation of concrete structures
The first year of the PhD project has involved a literature study of existing applications of peridynamics, particularly with respect to brittle materials, and secondly, the optimisation of concrete structures and its challenges. In addition, computational work has involved the setup of a concrete-only peridynamic analysis model within a CAD environment, considering a simple uniaxial cube test. The CAD environment is well suited to the geometry definition of unconventional, fabric-formed elements and allows for an integrated model incorporating geometry/constructability requirements, analysis and a structural optimisation procedure. This process will allow for improve material reductions, and therefore embodied carbon, in the design and construction of un-conventional concrete structures.
Current work includes expanding the capabilities of the analysis model to additional analyse fibre-reinforced polymer (FRP) reinforcement bars. This will be validated using a simple pull-out test and will be compared to real test data. Additional studies regarding the discretisation and parallelisation of the model are also taking place.
