Advanced Engineering Materials, EarlyView.This article introduces an automated approach for converting the raw research data (use case of low‐cycle‐fatigue testing dataset) to machine‐readable resource description framework ones and storing them in an open digital repository. As two main prerequisites for this data digitalization process, the development of fatigue testing ontology and ckan ...

Sub-Millimeter-Scale Measurement of Local Convective Heat Transfer Coefficient Exceeding 100 W/(m^2-K) Using an Optical Pump-Probe Method [PDF]
Measurement, 249 (2025) 117001Conventional methods for measuring the local convective heat transfer coefficient (h_c) often rely on simplifying assumptions that can compromise accuracy. Pump-probe methods like time-domain thermoreflectance (TDTR) avoid these assumptions but are limited to h_c values larger than 30 kW/(m^2-K) due to modulation frequency constraints.

Advanced Engineering Materials, EarlyView.The study presents an efficient simulation approach for the polymer laser powder bed fusion process polymers process, validated with polyamide 12, polyamide 6, and polyetherketoneketone. It shows that inter layer time affects part density, with 90s yielding dense parts.

Heat Transfer between Graphene and Amorphous SiO2 [PDF]
arXiv, 2010 We study the heat transfer between graphene and amorphous SiO2. We include both the heat transfer from the area of real contact, and between the surfaces in the non-contact region. We consider the radiative heat transfer associated with the evanescent electromagnetic waves which exist outside of all bodies, and the heat transfer by the gas in the non ...
