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...

Woven fabrics UMAT- a coupled material model

02 Aug 2017 | Contributor(s): Ali Roumani

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...

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...
