Abstract


Paul Calvert's picture

NMT Biomechanics Why is it better to be seaweed better than to be phytoplankton?

This is an introductory post to a discussion on the advantages of multicellular organisms over single-celled eukaryotes from an energy harvesting viewpoint.  It is intended for the New Mexico Tech biomechanics class but others can play.

As engineers we should seek for a numerical measure (or some measures) that allows us to decide how close an organism is to the optimum.  Consider two cases: a seaweed in comparison to a single-cell photosynthetic eukaryote and a herbivore in comparison to a single-celled eukaryotic animal.

Comment on the possible answers, problems with the answers you previously gave or improve on the question.  You will be graded on the quality of your comments over the next two weeks.

Common questions about developing educational apps

This afternoon, I had an extremely pleasant Google hangout with Daniel Suo, and Professors Zhigang Suo and Teng Li . Our main focus was on brainstorming ideas on how to improve the user experience on iMechanica. After an hour or so our conversation drifted towards educational topics including novel ways of incorporating technology in STEM education.

Navier-Stokes model with viscous strength

In the laminar mode interactions
among molecules generate friction between layers of water that slide with
respect to each other. This friction triggers the shear stress, which is
traditionally presumed to be linearly proportional to the velocity gradient.
The proportionality coefficient characterizes the viscosity of water. Remarkably,
the standard Navier-Stokes model surmises that materials never fail – the transition
to turbulence can only be triggered by some kinematic instability of the flow. This
premise is probably the reason why the Navier-Stokes theory fails to explain

Three-dimensional simulation of crack propagation in ferroelectric polycrystals: Effect of combined toughening mechanisms

We simulate the fracture processes of ferroelectric polycrystals in
three dimensions using a phase-field model. In this model, the grain
boundaries, cracks and ferroelectric domain walls are represented in a
diffuse way by three phase-fields. We thereby avoid the difficulty of
tracking the interfaces in three dimensions. The resulting model can
capture complex interactions between the crack and the polycrystalline
and ferroelectric domain  microstructures. The simulation results show
the effect of the microstructures on the fracture response of the
material. Crack deflection, crack bridging, crack branching and
ferroelastic domain switching are observed to act as the main fracture
toughening mechanisms in ferroelectric polycrystals. Our fully 3-D

Instability of supersonic crack in graphene

The velocity and instability of crack motion in 2D hexagonal lattice of graphene under pure opening loads
are investigated by atomistic molecular dynamics simulations. The brittle crack along zigzag direction
in a strip can propagate supersonically at even 8.82 km/s under uniform normal loading of edge
displacements. Crack moving straightly at low speeds produces atomically smooth edges, while kinking
occur beyond a critical speed around 8.20 km/s equivalent to 65% of Rayleigh-wave speed in graphene,
which validates previous theoretical predictions of rapid fracture instability in elastodynamics, and
rough and irregular edges with oscillatory overhangs are formed subsequently.
