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...

Fatigue cracking of viscoelastic asphalt composite materials is one the major distresses in pavements. To quantify weakening effect fatigue cracks on mechanical properties materials, this study takes an asphalt-filler system as example, and micromechanics models are proposed by combining Eshbely’s equivalent inclusion theory Mori-Tanaka approach. Dynamic shear rheometer (DSR) tests performed sy...

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...

We propose in this paper a novel hybrid numerical modeling method for computing electromagnetic scattering from inhomogeneous targets containing honeycomb structures. In the proposed approach, whole structure is divided into inner and outer two subregions. Each thin wall of unit cell subregion replaced by zero-thickness surface, with aid resistive sheet boundary condition (RSBC) to describe ele...

Abstract In this article, the damped nonlinear transient response of a smart sandwich plate (SSP) comprising agglomerated CNT-reinforced porous nanocomposite core with multifunctional magneto-piezo-elastic (MPE) facesheets, subjected to thermal environment, is numerically investigated. The synergistic influence agglomeration, porosity and pyro-coupling on vibration control studied for first tim...
