In this work, we were able to improve existing residual stress measurement capabilities so that we could measure smaller length scales. We were able to measure residual stresses that oscillated from build layer to build layer (0.5 mm thick) in an additively manufactured part. The oscillations persisted over nearly 30 layers!

The loss of connectivity in particle-based LiMO2 (M = Ni, Co, Al, and/or Mn) electrodes due to mechanical failure
and fracture at the interface between primary particles is one of the major causes of capacity fading in Li-ion
batteries (LIBs) after certain electrochemical cycles. In this study, a model of a secondary particle composed
of randomly distributed primary particles is established using a fractal algorithm. The finite element method
with cohesive crack modeling is employed to simulate the intraparticle fracture within the secondary particle.

I have an opening PhD Position at our Institute of Mechanics, Otto von Guericke University Magdeburg (Germany).
The candidate should work in the field of new solution algorithms for complex simulations.
Additionally, the willingnes of teaching (in english as well as in german) is premised.
Attached you will find the corresponding job advertisement.

https://www.sciencedirect.com/science/article/pii/S0950061818322116 The mechanical behavior of masonry materials has a common feature: a nonlinear behavior with high compressive strength and very low tensile strength. As a consequence, old masonry buildings generally present cracks due to permanent loads and/or accidental events. Therefore, the characterization of the global dynamic behavior of masonry structures should take into account the presence of existing cracks.
