  1. VUMAT of a Generalized Standard Continuum Damage Model

    13 Apr 2018 | Downloads | Contributor(s):: Zhenyuan Gao, Liang Zhang, Wenbin Yu

    Based on a recently developed generalized standard continuum damage model (CDM), this VUMAT user subroutine provides a rigorous and robust framework for implementing various damage behavior into 2D or 3D solid elements in a finite element analysis (FEA). It is designed to be used with...

  2. PreVABS

    16 Nov 2017 | Downloads | Contributor(s):: Su Tian, Xin Liu, Wenbin Yu

    PreVABS is a pre-processing tool for VABS and SwiftComp. This tool is designed to reduce the workload of preparing input files of beam cross sections for VABS and SwiftComp, and to make the process automatic for the design and optimization purpose. Cross sections with general and...

  6. Composite Stiffness Property Prediction

    07 Aug 2017 | Downloads | Contributor(s):: Joshua Morris

    Micromechanical models for the composite axial tensile, transverse tensile, and axial shear are combined into one tool with the objective of comparing their effectiveness as property prediction methods.  Rule of mixtures models (ROM) and the composite cylinder model (CCM) results for...

  7. 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...

  8. Woven fabrics UMAT- a coupled material model

    02 Aug 2017 | Downloads | Contributor(s):: Masoud Haghi Kashani, Masoud Hejazi, Abbas Hosseini, Farrokh Sassani, Frank Ko, Abbas S. Milani

    One of the advantages of woven fabrics over unidirectional prepregs is their superior formability thanks to the large shear deformation capability. There exists, however, a limit on the shear deformation of woven fabrics, namely the wrinkling. Applying tension to delay wrinkling during forming...

  9. Puck Failure Criteria

    31 Jul 2017 | Downloads | Contributor(s):: karan kodagali

    Composite materials have been established as competitive materials during the last few decades due to their high strength to l ow weight ratio among other advantages and are widely used in many industries. A recent study has found that the industrial usage of composite failure...
