Abstract

An introduction to Metal Additive Manufacturing (MAM) (e.g. different techniques, the metallurgy of common alloy-systems, existing challenges) will be given. The focus of the lecture will be on the employment of different simulation approaches to address MAM challenges and to enable exploiting the full advantage of MAM for the manufacture of structures with desired property and functionality.

Objective

The main objectives of this lecture are: - Acknowledging the possibilities and challenges for MAM (with a particular focus on mechanical integrity aspects), - Understanding the importance of material science and metallurgical considerations in MAM, - Appreciating the importance of thermal, fluid, mechanical and microstructural simulations for efficient use of MAM technology, - Using commercial analysis tools (e.g. ABAQUS) for simulation of the MAM process.

Content

- Introduction to MAM (concept, application examples, pros & cons), - Powder-bed and powder-blown metal additive manufacturing, - Thermo-fluid analysis of additive manufacturing, - Continuum-based thermal modelling and experimental validation techniques, - Residual stress and distortion simulation and verification methods, - Microstructural simulation (basics, analytical, kinetic Monte Carlo, cellular automata, phase-field), - Mechanical property prediction for MAM, - Microstructure and mechanical response of MAM material (stainless steel, Ti6Al4V, Inconel 718), - Design for additive manufacturing - Artificial intelligence for AM Exercise sessions use ABAQUS for analysis of MAM process. Detailed video instructions will be provided to enable students to set up their own simulations. Students can install the packages on their own systems.

Literature

No textbook is available for the course (unfortunately), since it is a dynamic and relatively new topic. In addition to the material presented in the course slides, suggestions/recommendations for additional literature/publications will be given (for each individual topic).

Examination

Type
end-of-semester examination
Mode
oral 20 minutes
In addition to the final oral examination, which accounts for 50% of the final grade, there is one compulsory continuous performance assessment. Six small simulation assignments will be introduced starting from the third week of the semester during exercise sessions. Individual students are expected to follow video instructions to set up a simulation case for each assignment in ABAQUS and submit a single-page report covering the simulation results and their personal interpretation of these results. Each report has a three-week submission period, during which the lecturer and teaching assistant will be available for discussion and support. The reports will be graded, and the average of the five best assignment grades will count towards 30% of the final course grade. Additionally, simulation projects will be assigned to groups of 4-5 people to be worked on throughout the semester. A dedicated session in mid-semester will focus on discussing project progress and providing advice to each group before they present their projects verbally and in a 5-page report in the last week of the semester. This will account for 20% of the final grade.
