<p>A fully funded thesis project is proposed at Ecole Polytechnique in Montreal, Canada to start in 2017.</p>
<p><img src="http://imechanica.org/files/reconf.jpg" alt="" width="243" height="150" /></p>
<p class="MsoNormal"><span lang="EN-US" xml:lang="EN-US">In most engineering applications, struc</span><span lang="EN-US" xml:lang="EN-US">tures are designed to be stiff so that the loads they carry do not deform them significantly. In nature, structures are usually compliant; that is especially true for terrestrial and aquatic plants. Plants rely on their flexibility to change form and reduce their drag when subjected to fluid flow. Flexibility allows plants to reduce their drag through <em>reconfiguration</em>, however it is well known in the Fluid-Structure Interactions community that flexibility can also lead to a loss of stability and thus increased dynamical loads. Fluttering flags are a good example.</span></p>
<p class="MsoNormal">In the proposed project, we will consider the limitation to reconfiguration brought by a dynamic loss of stability in constant uniform flow. To understand the trade-off that flexibility brings to real plants in terms of drag reduction and loss of stability, we will study an idealised two-dimensional system: a beam clamped at its centre and subjected to a normal flow. We will study how the beam bends in the flow statically when its rigidity is decreased until a critical value is reached and the beam starts fluttering. The impact of the project will come from a better understanding of the natural adaptation of plants to wind stresses, but also in developing a new expertise in aeroelasticity of soft structures such as compliant drones.</p>
<p class="MsoNormal">The project is experimental and numerical in nature. The role of the student will be to perform wind tunnel measure campaigns as well as work on the development of a numerical procedure coupling an aerodynamics code to a finite element solution of the dynamical large deformation Euler-Bernoulli beam equation. The candidate sought has a masters in Mechanical/Aerospace Engineering and processes a strong background in fluid mechanics, vibrations, and numerical methods. Preferably, (s)he has some experience with computational fluid dynamics, finite element analysis and wind tunnel tests. A PhD thesis lasts approximately four years. The candidate will spend her/his time on the main campus at École Polytechnique de Montr<span lang="EN-US" xml:lang="EN-US">éal</span>. The candidate should be ready to start the project by January or May 2017. The financial aid is 20 000$CAD per year and is not taxable. PhD candidates must pay tuition (<3000$/year).</p>

<p><span>Focus Session on Reconfiguration</span></p>
<p><span>Reconfiguration is the passive deformation of sessile organisms </span><span>subjected to fluid flow. It confers an advantage to the organism in </span><span>terms of minimised drag and fluid loading in comparison to an </span><span>equivalent rigid structure. Trees bending under the wind, giant kelp </span><span>blades aligning together under tidal flows, sea grass subjected to</span><br /><span>wave action, or sea fans swaying with the waves are only a few </span><span>examples of reconfiguration. The study of reconfiguration is of </span><span>fundamental interest in biology to understand how sessile organisms </span><span>adapt to their environment. It is also critical to better predict and </span><span>avoid wind damages to crops, culture forests and urban trees during</span><br /><span>storms. The interaction between vegetation and water flow is important </span><span>in hydrology as it affects the flow resistance in vegetated channels.</span></p>
<p><span>The proposed session focuses on all aspects of reconfiguration </span><span>including, but not limited to, drag and loading, Vogel exponents, </span><span>elastic and brittle (pruning) deformations, static and dynamic </span><span>behaviors, stability, and it includes both wind and water flows. The </span><span>session scope includes the study of real biological organisms as well </span><span>as idealised simplified structures such as fibers, beams, rods, </span><span>membranes, plates or other bioinspired models which deform passively </span><span>under fluid flow. The goal of this fluid-structure interaction session </span><span>is to bring together researchers from different horizons of basic and </span><span>applied sciences to exchange on their different approaches to the </span><span>problem of reconfiguration.</span></p>

A funded Ph.D. positionin Mechanical Engineering is available at Polytechnique in Montreal, Canada. The work combines experimentations and theoretical modelling. The goal of the project is to use a fluid instability to fabricate intricate patterns at the microscopic scale. By fabricating fibers this way, interesting mechanical properties can be obtained depending on the parameters of the instability.
