Understanding of physical phenomena propagating across scales in the realm of materials engineering is key for designing new materials and structures that perform optimally under given engineering requirements.”

 

Research profile

Ondřej Rokoš is an Assistant Professor in the Mechanics of Materials section of the Department of Mechanical Engineering of Eindhoven University of Technology (TU/e). He is involved in teaching and research in the field of mechanics of materials. His areas of expertise include mathematical modelling, homogenization, computational mechanics, metamaterials, inelastic materials, quasicontinuum methods, molecular statics, digital image correlation, scanning electron microscopy, and stochastic structural dynamics.

His primary research interests are directed towards the understanding of physical phenomena propagating across scales in the realm of materials engineering. In particular, in identifying and describing the few important processes which usually emerge from smaller scale and which govern the overall behaviour of materials and structures at the engineering scale. Ondřej would like to use knowledge on these processes for the design of new materials that perform optimally under given engineering requirements.

Academic background

Ondřej obtained his PhD in Civil Engineering from CTU in Prague in 2014. His advisors were J. Máca and P. Kučera, and his thesis entitled “Dynamic analysis of grandstands” focused on stochastic modelling and lifetime predictions of grandstand structures subjected to random load. After his PhD, he held a postdoctoral position for several projects at CTU and TU/e, focusing on development of integrated experimental-computational micromorphic homogenization scheme for elastomeric mechanical metamaterials, multiscale identification of micromechanical parameters in heterogeneous solids, development of variational concurrent multiscale methodology for dissipative materials with discrete microstructures, modelling and homogenization techniques for optimal design of modular mechanical metamaterials with applications in soft robotics, and on improved transient stochastic analysis of grandstands. During his posdtoctoral period, Ondřej was a visiting researcher at the Eindhoven University of Technology (TU/e, 2015), where he worked with R.H.J. Peerlings on adaptive approaches for quasicontinuum method, and at the University of Luxembourtg (uni.lux, 2016), where he worked with S.P.A. Bordas and L.A.A. Beex on extended formulations for the quasicontinuum method. Ondřej became an Assistant Professor at TU/e in 2020.
