Experimental study; Generator composite; Self-powered sensor; Traffic flow monitoring

A zinc oxide (ZnO)/polyurethane (PU)-based generator composite was fabricated and its piezoelectric performances were examined in the present work. In addition, the influence of multi-wall carbon nanotubes (MWNTs) and copper powder incorporation on the piezoelectric performance of composites was also studied. The performance level of the composites with various ratios of the constituents was compared in terms of piezoelectric responses obtained from three different tests, i.e., foot stamping, vehicle loading, and cyclic wheel loading tests.

An analytical model to predict curvature effects of the carbon nanotube on the overall behavior of nanocomposites

CNT polymer nanocomposites; modelling; micromechanics;

In this study, analytical expressions are introduced to provide a better understanding of carbon nanotubes (CNTs) curvature on the overall behavior of nanocomposites. The curviness of CNT is modeled as the wave geometries, and the transformed physical characteristics are applied to micromechanical framework.

phase field model

In our recent work, we have developed a thermomechanical theory for multiphase flows, wich particular focus on the van der Waals fluid. By invoking Gurtin's microforce theory, the Coleman-Noll approach is generalized to derive constitutive relations in the presence of non-local effects. A new fully discrete numerical scheme for the model problem is designed. The scheme is provably unconditionally stable in entropy and second-order accurate in time. Using these technologies, the liquid-vapor boiling problem is investigated.

Submitted by Jie. Yin on

The Department of Mechanical Engineering, Temple University, seeks to recruit a pair of candidates: one an experimentalist, and the other a theorist with a strong background in scientific computation. 

The Department further wishes to focus its search for this pair of experimentalist/theorist scholars within one of the following two expertise areas:

    (1) thermo-fluids and energy,         (2) robotics and controls.

 

How to find RHT Concrete Parameters

Submitted by chasm9a on

concrete RHT 20mpa ansys autodyn abaqus

I want to perform simulation usinng Ansys Autodyn or Abaqus. Acutally I am new to FEM softwares. For the simulation I want to use RHT concrete model, however, the concrete is has f'c of about 3000psi or 20Mpa or less. Ansys Autodyn has RHT models for 35Mpa and 140MPa concrete and Abaqus has none. Kindly if you can help me find out the parameters for 20Mpa concrete. If any tests are needed to find the parameters, kindly provide me a list and refer me any source.
