TRANSIENT FORM FINDING, MECHANICAL MODELLING AND ASSESSMENT OF SEGMENTED FIBRE COMPOSITE SHELLS
The structural design aspect of co-design for long-spanning fibre reinforced polymer (FRP) structures will be developed in this project. This spans from early assessment during architectural design to detailed structural models informed by physical testing. Based on information from simulation of the winding process a global structural model, including information about the construction sequence, will be developed using dimensional reduction and homogenisation.
Realtime feedback during the design process will be enabled by developing a hierarchic modelling and discretization scheme, directly integrating CAD into structural modelling within the framework of isogeometric analysis, along with efficient solution strategies. Alternative measures for structural assessment will be developed to facilitate an interactive feedback on relevant structural properties during design space exploration.
