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
