DESCRIPTION:Gilad Yakir (FLEXLAB\, EPFL)\nAbstract:\nWe investigate the me
 chanics of a deformable solid of arbitrary geometry – a.k.a. “mechanic
 s potato” – in a rotating frame of reference (FoR). Newton’s equatio
 ns of motion formulated in a rotating FoR yield three ‘fictitious’ bod
 y forces: the centrifugal force (proportional to the square of the angular
  velocity)\; the Coriolis force (resulting from FoR-body relative motion)\
 ; and the Euler force (opposing angular acceleration). Whereas centrifugal
  forces in solid structures have been studied previously\, the combined ef
 fect of centrifugal and Euler forces remains unexplored. What is the mecha
 nical stress in a rotating arbitrarily shaped solid object? We conduct exp
 eriments using a precision apparatus with precise control over the angular
  dynamics. Digital image correlation is employed to measure the strain-ten
 sor components in rotating elastomeric samples with different shapes and d
 riving. Elasticity theory then enables access to the mechanical stress. Th
 ese experiments inform the development of a continuum mechanics model\, si
 mulated using the finite element method. Our findings offer potential for 
 broad applications: from advancing the design of rotating mechanical syste
 ms with novel functionalities to enhancing our understanding of deformatio
 n-induced traumatic brain injury.\n\nBiography:\nGilad is a Ph.D. student 
 at the École Polytechnique Fédérale de Lausanne (EPFL). He received his
  B.Sc. in 2018 and his M.Sc. in 2022 from the Technion – Israel Institut
 e of Technology. He conducted his Master’s thesis at the Nonlinear and C
 haotic Dynamical Systems research group under the supervision of Prof. Ode
 d Gottlieb\, where he researched the nonlinear oscillations and synchroniz
 ation of a multibody mechanical system.
