Advanced Engineering Materials, EarlyView.The share of technical thermoplastics is expected to grow further in the e‐mobility segment. In this study, a detailed temperature‐based tribological characterization of technical thermoplastics is performed. The tribological properties are discussed in terms of the dynamic mechanical properties of polymers at different ambient temperatures. A proof of

Advanced Engineering Materials, EarlyView.This study presents a 3D representative volume element‐based simulation approach to predict mesoscopic residual stress and strain fields in silicon solid solution‐strengthened ductile cast iron. By modeling phase transformation kinetics with an enhanced Johnson–Mehl–Avrami–Kolmogorov model, the effects of varying cooling rates on residual stresses are ...

Simulation of adaptive optical systems
17th Congress of the International Commission for Optics: Optics for Science and New Technology, 1996 A problem of simulation for an adaptive optical system realized as a discrete mirror consisting of a finite number of identical elements is solved. The authors have also investigated the control displacement of mirrors elements in accordance with variation of wave front set.
