Failure analysis in thin walled structures: smeared-based crack and delamination models
Prof. José Antonio Reinoso Cuevas (Universidad de Sevilla)

Fracture of thin-walled components can notably limit the performance of their corresponding engineering systems. This seminar is devoted to the analysis of failure in shells using novel smeared damage modelling strategies. In particular the main contents of the seminar concern: (1) the formulation of a consistent anisotropic damage model for laminated fiber-reinforced composites relying on the 3D-version of the Puck failure criterion, and (2) the
development of a new phase field model of brittle fracture for large deformation analysis of shells relying on a mixed enhanced assumed strain (EAS) formulation. Special attention is devoted to the applicability and versatility of such capabilities, emphasising the principal aspects with regard their formulation and numerical implementation.

14.30-15.30
Durability of photovoltaic modules: modeling, simulation and experiments
Prof. Marco Paggi (IMT School for Advanced Studies Lucca)

Photovoltaic modules based on Silicon solar cells show various sources of mechanical, optical and electrical degradation when exposed to the environment, including cracking in solar cells, decohesion of the backsheet, and aging of the polymer used to encapsulate the solar cells. These issues are currently under examination of the Task 13 technical group on Performance and Reliability of Photovoltaic Systems of the International Energy Agency. They are also under investigation within the ERC Starting Grant project “Multi-field and Multi-scale Computational Approach to Design and Durability of Photovoltaic Modules” supported by the European Research Council. In this seminar, experimental evidence of degradation phenomena is provided, along with novel mathematical models and computational methods for their effective simulation and understanding.
