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...

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...

Multiscale analysis of multilayer printed circuit board using Mechanics of Structure Genome

23 Jan 2019

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...

Abaqus plugins for Nonlinear Acoustics

06 Jul 2017

This paper introduces generalized tools in the form of plugins for a commonly used commercial finite element package Abaqus/Standard to model the nonlinear acoustic methods for detection of delamination damage in composite laminates. The nonlinear acoustic methods typically involve exciting a...

Injection Overmolding Manufacturing Process Simulation

29 Jun 2017 | Online Presentations

Injection over-molding or hybrid molding is a high-rate composites manufacturing process for fabrication of structural components with complex geometries.  The structural backbone is provided by a continuous-fiber woven prepreg while the geometric complexity is realized via injection...
