Histology-informed multiscale modeling of human brain white matter [PDF]
Scientific Reports, 2023 In this study, we propose a novel micromechanical model for the brain white matter, which is described as a heterogeneous material with a complex network of axon fibers embedded in a soft ground matrix.

Effect of fibre arrangement on the multiaxial fatigue of fibrous composites: a micromechanical computational model [PDF]
Fracture and Structural Integrity, 2015 Structural components made of fibre-reinforced materials are frequently used in engineering applications. Fibre-reinforced composites are multiphase materials, and complex mechanical phenomena take place at limit conditions but also during normal service

Micromechanical theory of strain stiffening of biopolymer networks [PDF]
Physical Review E, 2018 Filamentous bio-materials such as fibrin or collagen networks exhibit an enormous stiffening of their elastic moduli upon large deformations. This pronounced nonlinear behavior stems from a significant separation between the stiffnesses scales associated with bending vs. stretching the material's constituent elements.

Exploring the Limits of Euler–Bernoulli Theory in Micromechanics
Axioms, 2022 In this study, the limits of the Euler–Bernoulli theory in micromechanics are explored. Raman spectroscopy, which is extremely accurate and reliable, is employed to study the bending of a microbeam of a length of 191 μm. It is found that at the micro-scale, the Euler–Bernoulli theory remains an exact and consistent tool, and, possibly, other elasticity

Kinetic Theory Microstructure Modeling in Concentrated Suspensions
Entropy, 2013 When suspensions involving rigid rods become too concentrated, standard dilute theories fail to describe their behavior. Rich microstructures involving complex clusters are observed, and no model allows describing its kinematics and rheological effects ...

Micromechanical study of elastic moduli of loose granular materials [PDF]
, 2010 In micromechanics of the elastic behaviour of granular materials, the macro-scale continuum elastic moduli are expressed in terms of micro-scale parameters, such as coordination number (the average number of contacts per particle) and interparticle ...
