  1. A Last Paper: An Equivalent Plate Modeling of Corrugated Structures

    23 May 2014 | Publications | Contributor(s): Wenbin Yu, Zheng Ye, Victor Berdichevsky

    An equivalent classical plate model of corrugated structures is derived using the variational asymptotic method. Starting from a thin shell theory, we carry out an asymptotic analysis of the strain energy in terms of the smallness of a single corrugation with respect to the characteristic length...

  2. Accelerated Insertion of Advanced Materials for Aircraft Structures & Repair

    31 Oct 2014 | Publications | Contributor(s): Waruna Seneviratne, John Tomblin, Chee Chan, Tharindu Jayaratne

    Building block approach is a rational multi-level analysis and testing development approach used by many aerospace companies to certify metallic and composite structures. Costly and time-consuming allowable programs hinder application of novel composite materials and often forces designers to...

  3. Variational Asymptotic Modeling of Composite Dimensionally Reducible Structures

    09 Nov 2014 | Publications | Contributor(s): Wenbin Yu

    This is Prof. Yu's PhD dissertation. In this disseration, the variational asymptotic method has be used to provide a systematic, holistic, and rigorous approach to construct efficient yet accurate models for composite beams, plates, and shells.  

  4. Structure Genome: Fill the Gap between Materials Genome and Structural Analysis

    29 Nov 2014 | Publications | Contributor(s): Wenbin Yu

    A new concept, Structure Genome (SG), is proposed to fill the gap between materials genome and structural analysis. SG acts as the basic building block of the structure connecting materials to structures and the mechanics of SG governs the necessary information to link materials genome and...

  5. Pagano and Halpin - Influence of End Constraint in the Testing of Anisotropic Bodies

    06 Feb 2015 | Publications | Contributor(s): Nicholas Pagano, John Halpin

    Reading for 2/9/15

  6. A Critical Assessment of Computer Tools for Calculating Composites Wind Turbine Blade Properties

    16 Mar 2015 | Publications | Contributor(s): Wenbin Yu

    The purpose of this paper is to critically assess several computer tools for calculating the inertial and structural properties of wind turbine blades. The theoretical foundation of each tool is briefly summarized, and the advantages and disadvantages of each tool are pointed out. Several...

  7. Mathematical Construction of a Reissner–Mindlin Plate Theory for Composite Laminates

    03 Jun 2015 | Publications | Contributor(s): Wenbin Yu

    A Reissner–Mindlin theory for composite laminates without invoking ad hoc kinematic assumptions is constructed using the variational-asymptotic method. Instead of assuming a priori the distribution of three-dimensional displacements in terms of two-dimensional plate displacements as what...

  8. Micromechanics Simulation Challenge Level I Results

    30 Jun 2015 | Publications | Contributor(s): Andrew J Ritchey, Hamsasew Sertse, Johnathan Goodsell, Wenbin Yu, Byron Pipes

    The initial results of level I of micromechanics simulation challenge were documented in the attached paper which is also included in the proceedings of American Society of Composites 30th Annual Technical Meeting at Michigan State.  Results for various composites including fiber...

  9. Assess the Accuracy of the Variational Asymptotic Plate and Shell Analysis (VAPAS) Using the Generalized Unified Formulation (GUF)

    19 Nov 2015 | Publications | Contributor(s): Wenbin Yu

    The accuracy of the Variational Asymptotic Plate and Shell Analysis (VAPAS) is assessed against several higher order, zig zag,and layerwise theories generated by using the invariant axiomatic framework denoted as Generalized Unified Formulation (GUF).These theories are also compared against the...

  10. Analysis of Slender Structures Using Mechanics of Structure Genome and Open Source Codes

    18 Apr 2016 | Publications | Contributor(s): Xin Liu

    This is the Master thesis from Xin Liu in Prof Yu’s research group. In this thesis, the Mechanics of Structure Genome (MSG) has be used to provide an alternative way to model composite beam-like structures. Basic concept of MSG is introduced as well as the idea of how to carry out...
