Job Description
Doctoral Researcher – Fatigue of WAAM Structures
Aalto University Department of Energy and Mechanical Engineering invites applications for a fully funded Doctoral Researcher position focused on fatigue modelling of Wire Arc Additive Manufacturing (WAAM) components and structures.
Responsibilities
- Conduct research on how WAAM-induced geometric and material imperfections affect fatigue strength.
- Identify repeating surface features in WAAM builds and investigate suitable geometry and material properties to quantify their effects on fatigue life.
- Perform theoretical and numerical modelling, validated with fatigue experiments.
- Study local geometry imperfections (e.g., undercuts) and their impact on local stress‑strain fields and fatigue crack initiation.
- Characterise as‑built surfaces and reconstruct them into high‑fidelity finite element models preserving key geometric features.
- Simulate local stress concentra...
