NICAS Colloquium Online

24 February @ 12:00 pm - 1:00 pm CET

We are pleased to announce a new, online edition of the NICAS colloquium on Thursday 24 February 2022 from 12.00 to 13.00 hrs. The colloquium will take place online through Microsoft Teams

 

Throughout the year, NICAS organises a bi-weekly Colloquium consisting of two short research lectures. It provides researchers with the opportunity to present ideas for, updates on or results of their activities. The NICAS Colloquium allows people to stay informed on a regular basis about the latest developments and results of research and to exchange information and expertise.

 

 

The chair of this colloquium will be Annelena de Groot (NICAS Research Associate)

 

The presenter is:

 

 Gijs Eumelen – Chemo-mechanical model for degradation of oil paintings by amorphous and crystalline metal soaps

 

Abstract:

The formation of metal soap in historical oil paintings is associated to several degradation mechanisms, such as delamination, cracking and flaking of paint, which threatens museum collections worldwide. This presentation proposes a coupled chemo-mechanical model, which is capable of modelling amorphous and crystalline metal soap formation and the corresponding mechanical behaviour of the paint layer(s). The model is applied to analyse two numerical examples that are representative of typical metal soap-related degradation processes observed in historical oil paintings, revealing that the growth process and coalescence of crystalline metal soap aggregates, the deformation of the paint surface, and the consequent cracking and delamination patterns are predicted in a realistic fashion.

 

Bio:

Gijs Eumelen is a PhD student within the Department of the Built Environment at Eindhoven University of Technology (TU/e) since 2017, where he is supervised by prof. dr. ir. Akke Suiker and dr. ir. Emanuela Bosco. In his research, Gijs focuses on numerically modelling the chemo-mechanical behaviour of paint layers as a result of metal soap formation. Before his role as a PhD student, Gijs obtained a Master’s degree (cum laude) in Structural Engineering and Design from the TU/e.
