1 Introduction: BK50A2700 Selection Criteria of Structural Materials D.Sc Harri Eskelinen
2 Briefly about the lecturer… Harri Eskelinen, GSM ,Senior Research Scientist at LUT since 1999, before that lecturer and assistant since 1985.Since 2011 nominated as an adjunct professor.Since 2014 Head of the Master Degree Programme in Mechanical EngineeringD.Sc (Mech.eng.) 1999Main research topics:DFMAMW-mechanicsGreen technology in material selectionDistance learningSupervising following courses:Technical Drawing and 3D-modellingMaterial ScienceEngineering Design and MechanismsMachine Element DesignResearch Methods and Methodologies
3 Learning outcomesAfter having passed this course the student is able to:apply and develop systematic and analytical means and tools of systematic material selection approaches into solving cross-technological material´s selection tasksdefine and analyze the properties, the strengths, the weaknesses and the application areas of the main groups of constructional materials for different types of applicationsjustify and build generalized models to take into a count both the functionality and the manufacturability aspects in addition to the total costs and environmental aspects of the product in solving the material selection taskevaluate and utilize recent results and documents of material sciencederive analytical models based on the principles of LCC’s, LCA’s and MIPS-factors in material selection.
5 ContentDuring the course the student will become familiar with the properties and application areas of different constructional materials.The recent scientific results dealing with material science and technology will be discussed.Aspects of selecting and comparing different materials (metals and their alloys, polymers, ceramics, composites, wood materials, adaptive materials, nanomaterials) are discussed from the viewpoints of functionality, manufacturing aspects, costs and environmental aspects of the product.Future trends in materials science are discussed briefly. Innovative solutions of the material selection tasks will be discussed.Environmental aspects of material selection from the viewpoint of LCC and LCA and the basics of MIPS calculations.Principles to formulate and solve the materials solution tasks based on analytical and systematic approaches and means to develop models to support the selection process staring from the product’s requirement list will be discussed in details.Multi-language teaching environment will be utilized during the project work.
