Planar equilibria of an elastic rod wrapped around a circular capstan

Submitted by Harmeet Singh on Thu, 05/12/2022 - 13:58

research

We present a study on planar equilibria of a terminally loaded elastic rod wrapped around a rigid circular capstan. Both frictionless and frictional contact between the rod and the capstan are considered. We identify three cases of frictionless contact -- namely where the rod touches the capstan at one point, along a continuous arc, and at two points. We show that, in contrast to a fully flexible filament, an elastic rod of finite length wrapped around a capstan does not require friction to support unequal loads at its two ends.

Dear iMechanicians,

I hope you find the following article useful. We develop the first phase field fracture formulation for CNT-based composites. A mean-field homogenisation approach is combined with a micromechanical description of carbon nanotube's fracture and pull-out, including the agglomeration effect.

How to evaluate natural coordinates from global coordinates?

Ask iMechanica

For 3D isoparametric elements, we could easily find evaluate x(r,s,t), y(r,s,t) and z(r,s,t) from (r,s,t). Given a global point (x,y,z), how could we find/derive the corresponding nature coordinate (r,s,t)? Is there any equation? Even for linear element, the coordinate transformation is not linear.

This is a practical FEM implementation issue, if a user wants to query a displacement at a given global point, how can we do that? If we know the (r, s, t), then we could easily find the U(r, s, t) = ΣN_i(r, s, t)U_i

Postdoc Position

I am looking to recruit a high motivated and independent postdoctoral researcher to study, through theoretical and computational approaches, various topics related to the topological mechanics of solids, including phononic topological insulators, odd elasticity, and non-Hermitian mechanics. The position is available for an initial 8-month duration, with possible extension to 24 moths depending on availability of funding. The position is available immediately.
