  4. Dual Number Automatic Differentiation

    05 Jun 2014 | Downloads | Contributor(s): Wenbin Yu, kshitiz swaroop

    DNAD (dual number automatic differentiation) is a simple, general-purpose tool to automatically differentiate Fortran codes written in modern Fortran (F90/ 95/2003) or legacy codes written in previous version of the Fortran language. It implements the forward mode of automatic differentiation...

  5. Interlaminar Stresses in Symmetric Angle-Ply Laminates Subjected to Anticlastic Bending Deformation

    04 Jun 2014 | Tool Information | Contributor(s): Johnathan Goodsell

    The aim of the present work is to develop a solution for the interlaminar stress field in a symmetric and balanced,  angle-ply laminate subjected to anticlastic bending deformation.  Further, this class of problems is considered in order to elucidate the behavior of angle-ply laminates...

  6. 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...
