Braiding Simulation for Rtm Preforms

Braiding is a manufacturing process that is increasingly being used to manufacture pre-forms for Resin Transfer Moulding. A fast simulation method is presented for the prediction of the fibre distribution on complex braided parts and complex kinetic situations (e.g. changes in velocity, orientation). The implementation is suited for triangular surface representations as generated by many CAD so...

Imaging condition for elastic RTM

Polarity changes in converted-wave images constructed by elastic reverse-time migration causes destructive interference after stacking over the experiments of a seismic survey. The polarity reversal is due to the fact that S-mode polarization changes as a function of direction, and therefore the imaged reflectivity reverses sign at normal incidence. We derive a simple imaging condition for conv...
