Peter Göransson

Peter’s research interests are numerical modeling of coupled acoustics and vibrations phenomena, with special focus on finite element modeling of dissipation mechanisms and efficient computational methods for highly damped, layered structures. He has during his career been involved in a number of pioneering vibroacoustic modeling efforts which at the time constituted serious challenges to the available computational resources; e.g. during the early 90's the Noise Attenuation for Launchers project (funded by ESA estec) which resulted in 3D large scale models for spacecraft fairings of ARIANE 4 and 5 types with satellite dynamic response included; the ASANCA projects (funded by the European Commission) which resulted in a full scale 3D model of a Saab 340 fuselage cabin with interior trim modeled and a demonstration of the applicability of finite element modeling for the transmission of noise and vibrations in such a system; the fundamental research BRAIN project (funded by the European Commission) which resulted in an important step forward in the elastoacoustic modelling of fibrous porous materials in the noise and vibration transmission through double wall structures with sound proofing. He has participated in more than 10 EU collaborative research projects.

With the establishment of the Centre for ECO2 Vehicle Design in 2006, he extended his research interests to sustainable design based on multi-functional structural components which are optimised to satisfy contradictory functional requirements, e.g. structural load carrying paired with acoustic performance at lowest weight, complexity, cost, environmental impact etc. 

Recently his research focus is on inverse characterisation of anisotropic solid materials including mechanisms of dissipation, micro-to-macro based modelling of the acoustics of poroelastic cellular materials, characterisation and modelling of acoustic meta-materials based on distorted cellular geometries, topology optimisation of structures under multi-functional constraints, performance optimisation of multi-functional and multi-layered structures, and the Life cycle energy optimisation method,
