151-0544-00L  Metal Additive Manufacturing - Mechanical Integrity and Numerical Analysis

SemesterFrühjahrssemester 2019
DozierendeE. Hosseini
Periodizitätjährlich wiederkehrende Veranstaltung

KurzbeschreibungAn introduction to Metal Additive Manufacturing (MAM) (e.g. different techniques, metallurgy of common alloy-systems, existing challenges) will be given. The focus of the lecture will be on employment of different simulation approaches to address MAM challenges and to enable exploiting the full advantage of MAM for manufacture of structures with desired property and functionality.
LernzielThe main objectives of this lecture are:
- Acknowledging the possibilities and challenges for MAM (with particular focus on mechanical integrity aspects),
- Understanding the importance of material science and metallurgical considerations in MAM,
- Appreciating the importance of thermomechanical, microstructural and continuum mechanics simulations for efficient use of MAM technology.
InhaltPreliminary schedule:
- Introduction to MAM (concept, application examples, pros & cons),
- MAM techniques (SLM, EBM, DED, etc.),
- Metallurgy of MAM alloy-systems (stainless steel, Al, Ti, superalloys),
- Thermal analysis of MAM process,
- Microstructure of MAM builds (experimental observations and modelling),
- Stress analysis for MAM (distortion and residual stress, residual stress measurement techniques),
- Imperfections in MAM (porosity, lack of bounding, etc.),
- Post-processing and heat treatments for MAM builds (experimental observations, simulation),
- Mechanical behavior of MAM materials (tensile, hardness, fatigue, creep),
- Mechanical integrity analysis of MAM parts,
- Design for MAM,
- Lattice structures (types, characteristics, mechanical analysis),
- Recent advances in MAM, business cases, expectation for future of MAM.
