1. Remote Acoustic Characterization of Thin Sheets
Abstract : There is a need to monitor the existence and effects of damage in structural materials. Aircraft components provide a much publicized example, but the need exists in a variety of other structures, such as layered materials used in food packaging industries. READ MORE

2. Modelling Aspects in Forming and Welding of Nickel-Base Superalloys
Abstract : The reduction of fuel consumption and carbon dioxide emissions are currently a key factor for the aviation industry because of major concerns about climate change and more restrictive environmental laws. One way to reduce both fuel consumption and CO2 emissions is by significantly decreasing the weight of vehicles while increasing the efficiency of the engine. READ MORE

3. Numerical Modelling of Dynamics of Light Porous Materials
Abstract : Porous materials are among the most commonly used materials for noise and vibration reduction in modern transportation vehicles. To design, industrially relevant, weight and cost effective noise and vibration measures, there is a need for general prediction models capable of representing the elasto-acoustic behaviour of such materials.

4. The use of Textiles in an Acoustic Context
Abstract : Working with textiles in an acoustic context gives enormous possibilities to combine the acoustic function of materials with the visual function (aesthetics). Depending on the material choice and the production techniques, textiles may for instance be flexible, stiff, airtight, have high density or high porosity. READ MORE
