  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. The Integration of Composite Constituent-Level Failure Models During Composite Size Optimization

    25 Nov 2014 | Publications | Contributor(s): Robert N Yancey

    A number of structural optimization methods have been applied over the years to aid in the design process for structural components. The design criteria are often based on stress, strain, or displacement allowables that can be easily calculated with any finite element analysis model. For...

  5. 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...

  6. Mechanics of Composites Materials and Laminates: Lecture notes for AAE 555

    18 Dec 2014 | Publications | Contributor(s): C.T. Sun

    Professor C.T. Sun's lecture notes for AAE 555: Mechanics of Composite Materials. Note that all 7 chapters are available under the "additional materials available" link located beneath the "Download" button. "Download" downloads only the 1st chapter.

  7. 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

  8. 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...

  9. 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...

  10. 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...
