Dr Rainer Groh

Biography

Rainer Groh is a Research Fellow of the Royal Academy of Engineering in the Department of Aerospace Engineering. After graduating with a MEng in Mechanical Engineering from the University of Bath in 2011, Rainer completed his PhD at the Centre for Doctoral Training of the Bristol Composites Institute in 2015. While the research of his PhD thesis focused on modelling 3D stress fields in highly heterogenous and variable-stiffness composite laminates, his current research lies in the stability and bifurcation analysis of slender engineering and biological structures. Specifically, his work couples nonlinear finite element methods with numerical continuation algorithms to uncover and understand the oftentimes complex branching behaviour of slender load-bearing structures. One particular example is the formation and growth of localised post-buckling patterns in an axially compressed cylinder. Current research projects include: (a) modelling of complex, interacting instabilities and robust design approaches to account for them; (b) designing imperfection insensitive nonlinear structures; (c) experimental path-following, i.e. replicating the versatility of established numerical tools available for analysing nonlinear structures in an experimental setting; and (d) modelling of growth induced instabilities in soft matter.
