ESR 11:
Davide Manfredo

I am Davide Manfredo and I have completed my Master’s degree in Mathematics for Life Sciences at Università di Trento, in Italy. After finishing my Bachelor’s degree in pure Mathematics at Università di Torino, I decided that applied mathematics was what I wanted to build my professional career on. During my academic path, I also had the chance to study in France and Thailand, and do an internship in Spain and these experiences had a great impact on the person I am today.

Thanks to my Bachelor’s degree I have a solid base in pure mathematics and during my Master’s degree, I have been able to specialize in numerical analysis, simulations, and coding. Despite my Master’s degree focused more on biomedical applications, I think that the strength of mathematics is its versatility and this is what makes this discipline so powerful and fascinating.

I am confident that working in the THREAD project will undoubtedly not only improve my scientific expertise but will also allow me to meet inspiring people and make me discover new aspects of the world around me.

Description

The ESR will develop more complex, inelastic – i.e. viscoplastic, or frequency dependent viscoelastic – constitutive models, formulated on the level of sectional quantities and thus improve the state of the art in Cosserat rod theory in industrial applications. On the basis of properly devised experiments, such models will be formulated and parameters will be identified. The interpretation of the results of experiments conducted by ESR11 in the lab at ITWM is complemented by virtual experiments, utilising the codes developed by ESRs of work package 1. The ESR will investigate the numerical aspects related to the necessary extension of the discrete Cosserat rod model and its efficient implementation in close cooperation with ESR1.

Expected Results

(a) Test rig experiments and virtual experiments will provide the basis for the development of a model based identification of effective constitutive properties of cables and hoses. (b) The resulting effective constitutive models, formulated on the level of sectional quantities, will be utilized for an enhancement of the discrete Cosserat rod model developed at ITWM. (c) The enhanced rod model will be applied for further simulation based investigations of inelastic effects appearing in practically relevant use case examples, which will be supplied by the supporting partners fleXstructures GmbH and Industrial Path Solutions Sweden AB of THREAD.
