Thin films usually exhibit instabilities and yield intricate wrinkles when two clamped ends are twisted. Here, we explore the wrinkling behavior and pitch-fork bifurcation of twisted thin films experimentally and theoretically. To quantitatively predict the post-buckling evolution of twist-induced wrinkling morphology, we develop a refined finite-strain plate model derived from 3D field equations and then solve it by using the finite element method with COMSOL. We examine the effects of aspect ratios and pre-tension on the wrinkling profile.

Ph.D. position at the Technion – Israel Institute of Technology.  The research is concerned with experiments and modeling of failure and fracture in soft materials.  Preference will be given to candidates with background in nonlinear finite element methods and constitutive modeling. If you are interested, please send an email to me at: cvolokh [at] technion.ac.il (cvolokh[at]technion[dot]ac[dot]il) with a single PDF file containing your CV, g

A bistable curved beam with magnetic torque-driven actuation has the potential for fast and untethered reconfiguration of metamaterials. However, no modeling method of a bistable curved beam whose instability is coupled with an external magnetic field for the design of active metamaterials. A bistable curved beam's second mode (S-shape) generation is essential for a multimodal and multistep reconfiguration of metamaterials, which was not explored before.

My lab is looking for strongly motivated Ph.D. students and Postdocs to join our group in the Department of Mechanical Engineering & Materials Science at Duke University. We conduct research on human-centered materials intelligence through a combination of flexible electronics, robotic metamaterials, and artificial intelligence. Two positions are available immediately. 

Position 1: The project will focus on the design, fabrication, and testing of robotic mechanical metamaterials.

In the works below, an isogeometric analysis combined with adjoint sensitivity analysis is used for the design of mechancial metamaterials. A detailed introduction to isogeometric analysis (IGA), formulation and implementation of adjoint sensitivity analysis in the nonlinear regime for auxetics design is included in the thesis and papers below. The work presents a holistic physics-based approach for structural shape optimization using IGA. Kindly cite the work if you find useful.
