Abstract: A two-component network is studied by Monte Carlo simulation to model the lipid/spectrin membrane of red blood cells. The model predicts that the shear modulus decreases rapidly with the maximum length of the model spectrin and should be in the 10-7 J/m2 range for human red blood cells. A simplified model for the isolated spectrin network shows a negative Lame coefficient λ. Transverse fluctuations of the dual membrane are found to be fluidlike over the range of wavelengths investigated.

Non-linear and non-local transport processes in heterogeneous media: from long-range correlated percolation to fracture and materials breakdown
TL;DR: In this article, the authors review and discuss recent progress in modelling non-linear and non-local transport processes in heterogeneous media, and the interplay between the nonlinearity and nonlocality is discussed in depth with the aim of establishing that, often non linearity andnon-locality are "two sides of the same coin" such that one may have no meaning without the presence of the other one.

Multiscale simulation of erythrocyte membranes
TL;DR: A multiscale method to correlate distributions of internal stress with overall cell deformation is developed and predicts correlation between the occurrence of Sp unfolding and increase in the mechanical load upon individual skeleton-bilayer pinning points.

Modeling and prediction of flow-induced hemolysis: a review
TL;DR: This review summarizes approaches to continuum-level modeling of hemolysis, a method that is likely to be useful well into the future for design of typical cardiovascular devices and to validate numerical simulations.

Thermally induced proliferation of pores in a model fluid membrane.

TL;DR: Permeabilization of lipid bilayers by certain peptides involves perturbing lipid-lipid cohesive energies, and simulations show that at small line tensions the entropy of hole shape fluctuations destroys the model membrane's stability.

Elastic Properties of Lipid Bilayers: Theory and Possible Experiments
TL;DR: A theory of the elasticity of lipid bilayers is proposed and it is argued that in the case of vesicles (= closed bilayer films) the only elasticity controlling nonspherical shapes is that of curvature.

TL;DR: In this article, the interplay between crystalline (or hexatic) order and thermal fluctuations in membranes with vanishing surface tension is studied, and a finite temperature crumpling transition is predicted for crystalline membranes.

TL;DR: In this paper, the shape of G is universal and involves only one characteristic length λ(ω) varying like ω-n, where 0.12 < n < 0.19 and 1.30 < m < 1.45.

TL;DR: The product of the elastic area compressibility modulus, the thermal area expansivity, and the temperature gives the reversible heat of expansion at constant temperature for the bilayer.
