Fiber bundle model of thermally activated creep failure
Stefan Hiemer, Paolo Moretti, Stefano Zapperi +1
An equal load sharing fiber bundle model for thermally activated breakdown is developed using transition state theory to describe the rate of elementary failures. The lifetime dist…

X-ray particle tracking velocimetry for steady-state rheological characterization: Case study of a complex polymer melt flow in material extrusion additive manufacturing
Julian Kattinger, Stefan Hiemer, Mike Kornely +4
We introduce X-ray Particle Tracking Velocimetry (XPTV) as a promising method to quantitatively resolve the velocity field and associated rheological information of polymer melt fl…
