23 Jan 2019 | Contributor(s):: Fei Tao, Xiuqi Lyu, Xin Liu, Wenbin Yu
The structure of Printed Circuit board (PCB) is very complicated because it consists of woven composites and custom defined conducting layers. To improve the reliability of PCB, it is critical to predict the constitutive relations accurately. This study by implementing Mechanics of Structure...
Free Edge Stress Analysis of Laminated Structures with Arbitrary Cross Sections Using Mechanics of Structure Genome
12 Dec 2016 | | Contributor(s):: Lingxuan Zhou
This is the master thesis from Lingxuan Zhou advised by Prof. Yu. In this thesis, free-edge stress analysis of composite laminated structures with arbitrary cross sections is dealt with using mechanics of structure genome (MSG). A cross-sectional analysis specialized from MSG is...
A Novel Approach to Analyze Beam-like Composite Structures Using Mechanics of Structure Genome
08 Sep 2016 | | Contributor(s):: Xin Liu, Wenbin Yu
A novel approach to the analysis of beam-like composite structure is introduced in this paper. New software Gmsh4SC is developed based on two well-known open source codes Gmsh and CalculiX. One-dimensional Euler-Bernoulli and Timoshenko type finite elements are derived based on the constitutive...
Generalized Free-Edge Stress Analysis Using Mechanics of Structure Genome
22 Aug 2016 | | Contributor(s):: Bo Peng, Johnathan Goodsell, Byron Pipes, Wenbin Yu
This work reveals the potential of mechanics of structure genome (MSG) for the free-edge stress analysis of composite laminates. First, the cross-sectional analysis specialized from MSG is formulated for solving a generalized free-edge problem of composite laminates. Then, MSG and the companion...
A Unified Theory for Constitutive Modeling of Composites
18 Apr 2016 | | Contributor(s):: Wenbin Yu
A unified theory for multiscale constitutive modeling of composites is developed using the concept of structure genomes. Generalized from the concept of the representative volume element, a structure genome is defined as the smallest mathematical building block of a structure. Structure...
