Adaptive multiscale simulation of damage in composite structures

Mesh adaptivity plays a key role in the efficiency and precision of any finite element simulation. In order to achieve the required accuracy with minimal cost, goal oriented error estimation is needed to localize and locally improve the finite approximation only where it is required. Damage simulation is not an exception. The inverse problem adds a new source of error from the data, and consequently a new parameter for the definition of the mesh adaptivity to compute a solution in the order of the data precision.

The project, which has just started, aims to extend the work of the Legato team in Error Estimation, Inverse Problems and Bayesian Inference to the efficient estimation of the damage of a composites.
