A Code for Flexural Analysis of Thin-Walled Composite I-Beams with Sandwich Web and Bond-lines

02 Aug 2017 | Downloads | Contributor(s): Mo E. Asl

Composite I-beams have extensive applications in the aerospace industry, construction and light-weight engineering structures. In the utility-scale wind turbine blades, the spar-caps and the shear web compose an I-beam structure which is referred to as the backbone of the blade carrying the...

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...

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...

A Manufacturing Sensitive Design Strategy for Composite Materials Using Physical Modeling and Stochastic Simulation of Defects

02 Oct 2020 | Online Presentations | Contributor(s): Ramesh Talreja

This presentation outlines a strategy for designing composite structures accounting for the presence of defects that are inevitable in a practical manufacturing process. The essential ingredients of the strategy are incorporation of defects in physical models for assessment of composite...

A Semi-Discrete Model for Progressive Damage and Failure of Fiber Reinforced Laminates

15 Nov 2021 | Online Presentations | Contributor(s): Anthony M Waas

High-strength and high-stiffness carbon fiber-reinforced polymer composite laminates (CFRP) are being increasingly used for primary load bearing structures in many industries. The most common material system used is based on thermoset resins (matrix material), which come in the form of convenient...

A Unified Theory for Constitutive Modeling of Composites

18 Apr 2016 | Publications | 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...

A User Material Subroutine for Implementing Anisotropic Hyperelastic Model of Fiber-Reinforced Rubbers

01 Jul 2017 | Downloads | Contributor(s): Rui Li

This code is a user subroutine written in FORTRAN that can be implemented in the commercial finite element software ABAQUS (version 6.14) to model the constitutive behavior of knitted fiber reinforced rubbers.

A viscoelastic approach for modeling bending behavior in finite element forming simulation of continuously fiber reinforced composites

07 Aug 2017 | Publications | Contributor(s): Dominik Dörr, Fabian J. Schirmaier, Frank Henning, Luise Kärger

An approach for modeling rate-dependent bending behavior in FE forming simulation for either a unidirectional or a woven/bidirectional reinforcement is presented. The applicability of the bending model to both fiber architectures is guaranteed by introducing either an orthogonal or a...
