Prof. Patrick Townsend Valencia
Polytechnic University, Madrid, Spain

Biography: The development of new viscoelastic and auxetic composite materials is the focus of Prof. Patrick Townsend's research to prevent damage to reinforced plastic and fiberglass vessels from the impact produced by waves known as slamming phenomenon, improving their useful life by protecting the laminate from microcracks and detachments. With the insertion of hybrid modifications in composite materials, it represents a novelty for the design and construction of structures in engineering and development of new materials. A series of publications are currently available that show the evolution of the designs and their exhibition during ICMFM2026 will focus on the implications of the use of a generation of auxetic elements. The research has been carried out in the laboratories of the Escuela Superior Politécnica ESPOL of Ecuador, the Materials Research Center at the Polytechnic University of Madrid and in different shipyards building this type of hull planing vessel.

speech title "Design of a Spherical Shell Modified with Viscoelastic Laminates for Compression"

Abstract-The objective of this research work is to analyze the behavior of spherical GFRP shells subjected to a compression test, with and without viscoelastic modification. The specimens were designed to scale, replicating the dimensions of GFRP bulbs with measurements adapted to the testing machine. The study variables included the response to deformation and applied load, maintaining the same configuration and laminate thickness. Subsequently, the compression-displacement behavior was evaluated by applying a distributed force as external pressure to the hemisphere, until the first microfractures in the material were reached. Shells with viscoelastic material had fewer imperfections in their laminate, a greater stress developed with a lower deformation produced. This shows that the viscoelastic material improves the system's ductility due to its ability to absorb energy from external loads. Finally, this concludes that, at the same deformation, there is a 26% difference in increased load capacity with the viscoelastic modification. These findings therefore highlight the potential of viscoelastic materials to improve the structural strength of the structure without increasing its thickness. This contributes to a weight reduction and, therefore, a lower energy demand from the engine, favoring the sustainability of the vessels.
