This note discusses the Timoshenko–Ehrenfest beam theory and the Griffith fracture theory. Both were annunciated in the West in 1921, exactly a century ago. Much progress has been made in these fields. Discussing the deficiencies of the theories might pave way ahead.
Call for PhD student grants and applications
Location: Polytechnic University of Bari, Department of Mechanics Mathematics and Management (DMMM), Via Orabona 4 - 70125 Bari – Italy
Job Type: Full Time
Deadline: A few PhD positions will open soon and every year starting June 2022, deadline to be announced. The application will include CV but also a well written potential project which has to be preliminary discussed with the supervisors.
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.

We are pleased to invite you to the workshop “State of the art and challenges in the modelling and design of ultralightweight structures”, which will be held remotely on the 12th of May, starting at 8.45 am BST (UK time). Twelve international academic and industrial speakers will share their research on the characterization, modelling and design of ultralightweight materials and structures.

My group in the Department of Mechanical Engineering at Shiv Nadar University has an open JRF position funded by Naval Research Board DRDO. The successful candidate may get the opportunity to enroll in the Ph.D. program starting in Monsoon 2022, subject to fulfilling the requirements.
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.
Preferred qualifications for the postdoc position include:
