  1. Constitutive modeling for time- and temperature-dependent behavior of composites

    08 Jan 2020

    Structural integrity, durability, and thermal stability represent critical areas for adequately modeling the behavior of composite materials. Polymeric matrices are prone to have time-dependent behavior very sensitive to changes in temperature that influence the effective properties of the...

  2. MSC.Patran/Nastran-SwiftComp GUI

    01 Apr 2019

    A graphical user interface (GUI) has been developed to integrate SwiftComp into MSC.Patran/Nastran for constitutive modeling and providing the automated conversion of the MSG plate and beam stiffness matrix into MSC.Nastran shell and beam element properties and materials. In order to reduce...
