  1. Adaptive Multi-Scale & Multi-Fidelity Progressive Failure Analysis of Composites

    0.0 out of 5 stars 

    14 Nov 2022

    Although high-fidelity modeling of progressive damage has advanced our understanding of failure mechanisms in fibre-reinforced composites, such techniques are currently still too computationally intensive for direct application to composite structures. The multi-scale nature of damage in...
