Hello,
Clarification on creep
Hello,
My work is related to creep in ceramics. Often I find the relation between the creep strain rate and stress as:
creep_strain_rate = constant x stress x other_factors (1)
Dynamic response and localisation in strongly damaged waveguides
In this paper, we investigate the formation of band-gaps and localisation phenomena in an elastic strip nearly disintegrated by an array of transverse cracks. We analyse the eigenfrequencies of finite, strongly damaged, elongated solids with reference to the propagation bands of an infinite strip with a periodic damage.
Can an elastic rod attain self-encapsulation when loaded transversally at midspan?
Can an elastic rod attain self-encapsulation when loaded transversally at midspan?
The elastic rod assumes the form of a liquid drop at self-encapsulation!

The edge effect in open lipid bilayers
Highlights:
A model for the free energy of the edge of an open lipid bilayer is derived.
The derivation is based on the interactions of the molecules comprising the edge.
The derived model can be employed to study pore growth in open lipid bilayers.
The model captures bending and torsional energies of the edge, in addition to the line tension.
The molecular origins of spontaneous curvatures and elastic moduli are investigated.
