Develop a data-driven design methodology for mechanical components made of metamaterials and produced by additive manufacturing
Design, 2-scale optimisation and process optimisation of shock-absorption devices
Targeted applications
Bi-stable metamaterials to improve shock-absorption devices.
Regularly organised lattice metamaterials to improve dissipative absorbers.
Methodology
Developing a
process-(micro)structure-(structural)properties (PSP) linkage, with
Simulation
of the manufacturing process
Prediction
of microscale properties and geometry
Uncertainty
quantification at different scales
Stochastic
homogenisation
Optimisation of
The
manufacturing process
The
geometries at two scales (metamaterial and structural geometries)
To this end, current multiscale
Integrated Computational Materials Engineering (ICME) methodologies have to be
surpassed: the recent emergence of data-driven approaches in computational
mechanics offers a change of paradigm, which could make ICME approaches
realistic for process and 2-scale stochastic optimisation to be conducted through
the use of surrogate models
