We study the micromechanics of collagen-I gel with the goal of bridging the gap between theory and experiment in the study of biopolymer networks. Three-dimensional images of fluorescently labeled collagen are obtained by confocal microscopy and the network geometry is extracted using a 3d network skeletonization algorithm. Each fiber is modeled as a worm-like-chain that resists stretching and ...

One of the basic questions which as persisted in the field of heating theory is the still unresolved mechanical action of hair-cell transduction. The fundamental problem that has historically plagued researches is the discrepancy between mechanically measured tuning of basilar membrane motion and neurally measured tuning. Inthis paper we show that he difference between these two measures appear...

Natural materials boast remarkable mechanical performances in some cases unmatched by their synthetic counterparts, and for this reason, they have become an inspiration for the development of new materials. In highperformance natural materials such as nacre, bone, or teeth, stiffness and toughness are achieved with the staggered microstructure, where stiff inclusions of high aspect ratio are em...

A framework is presented that enables coupled multiscale analysis of composite structures. The recently developed, free, Finite Element Analysis – Micromechanics Analysis Code (FEAMAC) software couples the Micromechanics Analysis Code with Generalized Method of Cells (MAC/GMC) with ABAQUS to perform micromechanics based FEA such that the nonlinear composite material response at each integration...

Novel subject-specific high-order finite element models of the human femur based on computer tomographic (CT) data are discussed with material properties determined by two different methods, empirically based and micromechanics based, both being determined from CT scans. The finite element (FE) results are validated through strain measurements on a femur harvested from a 54-year-old female. To ...

This paper presents an overview of micromechanics analysis of piezoelectric composites. Developments in micromechanics algorithms, finite element, and boundary element formulation for predicting effective material properties of piezoelectric composites are described. Finally, a brief summary of the approaches discussed is provided and future trends in this field are identified.

The aggregate in an asphalt mixture is coated with mastic consisting of bitumen (dilute phase) and filler (particulates phase). interaction packing plays important role the properties mastics. micromechanics models from composite rheology can be used to predict stiffening effect a suspension. In this research, fillers was investigated based on mastic. frequency sweep tests dynamic shear rheomet...
