In this paperwe investigate themechanical behavior of carbonfiber composites,where the carbonfibers are coated with radially aligned carbon nanotubes. For this purpose we develop a general micromechanics method for fiber composites, where fibers are coated with radially aligned microfibers (‘‘fuzzy fiber’’ composites). The mechanical effective properties are computed with a special extension of...

The dependence relation between the macroscopic effective property and the microstructure of interpenetrating multiphase composites is investigated in this paper. The effective elastic moduli of such composites cannot be calculated from conventional micromechanics methods based on Eshelby s tensor because an interpenetrating phase cannot be extracted as dispersed inclusions. Employing the conce...

Consider heterogeneous elastic materials, modelled by a random stationary microstructure. The homogenized properties are deterministic. To compute them, one needs to solve auxiliary problems (the so-called corrector problems), which are set on the entire space. In practice, these corrector problems need to be approximated, and a usual approach is to consider a large but finite domain, on which ...

This study evaluated the potential of using poly(lactic acid)/poly(e-caprolactone) (PLA/PCL) blends for fused filament fabrication (FFF) and assembly with pure PLA biomedical applications. PLA/PCL binary were meltblended in a twin-screw extruder at different ratios (20/80 to 80/20) then formed into filaments calibrated diameter FFF. The microstructure, surface properties, rheological mechanical...

In this research, we developed a four-phase model, which takes the aggregate gradation and porosity into account in prediction of elastic modulus concrete, based on micromechanical theories. The model has been verified with experimental results. First, using Mori Tanaka differential self-consistent (DSC) methods, pores both mortar interfacial transition zone (ITZ) were homogenized. Then, contin...

Using multiscale models and homogenization methods the elastic properties of two important musculoskeletal mineralized tissues, the mineralized turkey leg tendon (in short mineralized tendon) and the osteon, are modeled and simulated at different length scales. Our first aim is to find homogenization methods which predict the apparent elastic properties of the investigated tissues numerical acc...

This work focuses on the effects of inclusion proximity elastic behavior dilute matrix-inclusion composites. Rigid or soft monodisperse spherical inclusions are considered with moderate volume fractions. To conduct this study, Representative Volume Elements (RVE) an effective local minimum distance between varying sphere’s radius and one-tenth built. Numerical finite element calculations RVE pe...

Abstract Mean-field homogenization is an established and computationally efficient method estimating the effective linear elastic behavior of composites. In view short-fiber reinforced materials, it important to homogenize consistently during process simulation. This paper aims comprehensively reflect expand basics mean-field anisotropic viscous properties show parallelism properties. particula...

A sentinel node biopsy (SNB) has been proved to be an accurate method to estimate the axillary lymph node status as a replacement for axillary lymph node dissection (AxLND) in patients with early breast cancer who have not been treated with neoadjuvant chemotherapy (NAC). We examined the feasibility and accuracy of performing SNB after NAC. Seventy breast cancer patients treated with NAC were e...
