Dr Sascha Eisenträger
Dr Sascha Eisenträger is Lecturer at the School of Civil and Environmental Engineering (CVEN) and member of the Centre for Infrastructure and Engineering Safety (CIES), where he will be developing his research in Computational/Numerical Mechanics. In this context, a special focus is placed on high order Finite Element Methods (FEM) and Fictitious Domain Approaches.
Sascha’s enthusiasm for computational mechanics began early in his career and since then he has continued to refine his approaches. His initial mechanical engineering studies were completed in Germany at the University of Magdeburg, where he also obtained a Doctor of Engineering (Dr.-Ing.). In his PhD thesis he investigated numerical methods for wave propagation analysis in the general framework of Structural Health Monitoring (SHM). Although initially applied to carbon-fibre reinforced plates and sandwich panels for aeronautical applications the developed methods are also applicable to civil infrastructure such as buildings and bridges, e.g., Sydney Harbour Bridge.
Computational mechanics, then, is essentially part of an inter-disciplinary approach to engineering. Reliable numerical methods must be validated by experiments. This ensures the high-fidelity prediction of physical phenomena in the analysis of innovative designs. Due to the generality of the numerical methods that have been developed over the last decade various areas of application are currently investigated ranging from explicit dynamics (wave propagation, impact, high-frequency loads) over acoustic meta-materials (reduction of noise pollution) to piezo-electric transducers (SHM, energy harvesting).
Sascha will be well supported at CVEN. Professor Chongmin Song (director at CIES; expert in Scaled Boundary FEM), Professor Wei Gao (expert in stochastic FEA) as well as Senior Lecturer Dr Elena Atroshchenko (expert in Isogeometric Analysis) share his enthusiasm for computational mechanics. Sascha’s presence at CVEN will expand the existing areas of expertise, while shared interests will facilitate collaboration. He is also keen to maintain his research connections with his German colleagues.
Additionally, Sascha would like to build more understanding between academia and industry. He sees the distinction between academic researchers and industry as being neatly articulated by the Pareto Principle: “80% of the work is completed in 20% of the time. To get to that final 20% of the work, a big time and resource investment is needed, but it is here that innovation, academic rigor and excitement lie. His desire is to see this distinction diminished through increased understanding between the sectors.
