Abstract

In the present contribution, a multiscale framework for nonlinear analysis of finite deformation of red blood cell (RBC) membrane is developed. The first-order Cauchy–Born rule is adopted to establish an atomistic enriched hyperelastic constitutive model and to develop macroscale stress–strain relat...

This development was partly motivated by the need for a more precise scheme for modeling membrane structures. The effectiveness of the proposed approach is affirmed by the better prediction of RBC membrane deformability in comparison with experimental and numerical results found in literature and a significant reduction in computational cost. Our approach enables precise characterization of the effect of varying microstructure parameters, physiological, and osmolality conditions on the deformability of RBC membrane.
