Abstract
  • Today nano scale materials are being used for wide range of applications. One promising topic in nano scale materials is using them for reinforcement of different polymeric materials to reach desirable stiffness properties. The stiffness of these materials is mostly found experimentally because the nanocomposite community lacks a decent analytical model that can provide a reliable prediction. Modeling can be done using both numerical and analytical methods. Numerical methods can be time-consuming, expensive and need the expertise to implement right assumptions and extrapolate useful data. But they can be more reliable, if done correctly, compared with the analytical method. Analytical methods use a mathematical equation that has been derived considering the physics of the problem. Analytical methods are equations that predict properties on nanocomposites based on properties of components at different conditions (e.g., temperature, and more) and are more desired. For this work, we used a new Monte Carlo finite element analysis (FEA) method as a numerical method to model the stiffness of different nanocomposites and compared them with different analytical models to find the most accurate model that can predict the stiffness of nanocomposites as a function of its components? properties. We then com- pared different models with experimental results using cellulose nanocrystal composites.

  • description.provenance : Rejected by Julie Kurtz(julie.kurtz@oregonstate.edu), reason: Rejecting for the following reasons -1) Abstract page, your second major is Wood Science, Wood Science and Engineering is the department name. So change - in Material Science and Wood Science and Engineering, to read - in Material Science and Wood Science2) Title page, change the commencement date on the bottom to read - Commencement June 20173) Approval page, change the 2nd signature line to read - Co-Major Professor, representing Wood Science. 3rd signature line shows Head of the Material Science Program and should be change to read - Director of the Material Science Program. 4th signature line shows Chair of the Department of Wood Science and Engineering and should be changed to read - Head of the Department of Wood Science and Engineering4) The heading Author List should be changed to - CONTRIBUTION OF AUTHORS Everything else looks good. Once revised, log back into ScholarsArchive and go to the upload page. Replace the attached file with the revised file and resubmit.Thanks,Julie on 2016-06-29T17:23:52Z (GMT)
