Advanced Engineering Materials, EarlyView.Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Caratheodory Measure of Cylinders [PDF]
Transactions of the American Mathematical Society, 1965 definition of measure due to Caratheodory and a modification of the definition due to W. Gross. Subsequently, A. P. Morse and Randolph [4] obtained positive results using Gillespie measure. As a result of the work of A. S. Besicovitch and P. A. P. Moran [l] and the author [2], the question was settled in the negative for Hausdorff measure.

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Detached-eddy simulation of flow around a circular cylinder in ground effect
, 2006 In this study we performed a detached-eddy simulation (DES) of flow around a circular cylinder placed near and parallel to a moving ground, on which no boundary layer developed to interfere with the cylinder.

Correlation functions on Cylinders
Physical Review Letters, 1994 We have obtained the complete finite-size structure of energy-density correlation functions at all temperatures defined for two-dimensional Ising models on cylindrical lattices, extending the original results of Hecht. This reveals novel structure in terms of winding numbers and confirms predictions from conformal invariance theory to leading order.

Advanced Engineering Materials, EarlyView.A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,
