11. Method Development for Characterisation of Superalloy used in Containment Design
Abstract : Due to the trend of increasing environmental demands put on civil aviation, manufacturersof commercial aircraft engines meet increased pressure to reduce weight. Modernturbofan engines represent up to almost one tenth of an aircraft's total weight, meaning areduction of engine component weight of just 30 kg is estimated to reduce CO2 emissionsby 400 tonnes over the lifetime of a medium sized commercial aircraft.

12. Compressive failure of unidirectional NCF composites
Abstract : With more people flying every year, new technologies are needed to reduce our impact on the environment. One option is to reduce the energy used in flight by introducing lighter materials such as carbon fibre reinforced polymers (CFRP). READ MORE

13. A Damage-Based Interface Model: Application to the Degradation and Failure of a Polycrystalline Microstructure
Abstract : A constitutive model for material interfaces is presented. The model is based on damage coupled to plastic (or viscoplastic) slip and dilatation, and it is able to describe the successive degradation and failure of an interface. READ MORE

14. As-cast AZ91D magnesium alloy properties : Effects of microstructure and temperature
Abstract : Today, there is an essential need for lightweight, energy-efficient, environmentally benign engineering systems, and this is the driving force behind the development of a wide range of structural and functional materials for energy generation, energy storage, propulsion, and transportation. These challenges have motivated the use of magnesium alloys for lightweight structural systems. READ MORE

15. Control of particles codeposition and strengthening mechanisms in nickel based nanocomposite coatings
Abstract : Surface durability is a key factor in the service life of components. Depending on the aggressiveness of the environment, surface deterioration by wear or corrosion leads to failure of the bulk material and eventually to the loss of functionality of the component. READ MORE
