Course Objective

The students having passed the exam in this course should have a deep understanding of The students having passed the exam in this course should have a deep understanding of selected topics in mechanical properties of thin films and should also be able to use this knowledge on own research problems. The aim of this course is to give the students an overview of mechanical properties of thin films. At the beginning thin film definition and its elastic and plastic deformation behavior are introduced followed by the description of the fracture behavior of thin films. The outline of thin film deflections and stresses are described with the compaction problems and suggested solutions. Nanoindentation, basic hardness testing, pile-up and sink-in are explained. As a final outline of scratch method is given
