This short course is comprised of four lectures:
- 14:00 – 14:45: Constitutive modeling enhanced by machine learning
Knut Andreas Meyer
The enhancement of traditional constitutive models by machine learning is paving the way for automatically discovering new and better models. This lecture gives an overview of recent approaches in physically constrained machine learning-enhanced constitutive models, while reviewing fundamental theories and discussing examples from the literature.
- 15:00 – 15:45: Inverse problems (deterministic)
Henning Wessels
Parameter identification approaches relying on full-field measurement data constitute an inverse problem. Adopting concepts discussed in the inverse problems community, we distinguish between all-at-once (or one-shot) and reduced approaches. With this general framework, we are able to structure a large portion of the literature on parameter estimation in computational mechanics.
