2. Shear Fracture and Delamination in Packaging Materials : A study of Experimental Methods and Simulation Techniques
Abstract : Packages are the means of preservation, distribution and convenience of use for food, medicine and other consumer products. Package opening is becoming complicated in many cases because of cutting cost in design and production of opening techniques. READ MORE

3. The influence of microstructure on mechanical and tribological properties of lamellar and compacted irons in engine applications
Abstract : Lamellar graphite iron (LGI) is commonly used in diesel engine applications such as piston rings–cylinder liner where an excellent combination of physical and tribological properties is essential to avoid scuffing and bore polishing issues. The excellent tribological behaviour of LGI alloys is related to the graphite lamellas, which act as solid lubricant agents by feeding onto the tribosurfaces under sliding conditions. READ MORE

4. On the deformation behavior and cracking of ductile iron; effect of microstructure
Abstract : This thesis focuses on the effect of microstructural variation on the mechanical properties and deformation behavior of ductile iron. To research and determine these effects, two grades of ductile iron, (i) GJS-500-7 and (ii) high silicon GJS-500-14, were cast in a geometry containing several plates with different section thicknesses in order to produce microstructural variation.

5. The effect of microstructural features, defects and surface quality on the fatigue performance in Al-Si-Mg Cast alloys
Abstract : Global warming is driving industry to manufacture lighter components to reduce carbon dioxide (CO2) emissions. Promising candidates for achieving this are aluminium-silicon (Al-Si) cast alloys, which offer a high weight-to-strength ratio, excellent corrosion resistance, and good castability. READ MORE
