First‐Principles Modeling of Solid Solution Softening and Hardening Effects in Al–Mg–Zr–Si Aluminum Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
The role of various alloying elements in face‐centered cubic aluminum on the barrier of a Shockley partial dislocation during its motion is presented. The study aims to understand how alloying atoms such as Mg, Si, and Zr affect the energy landscape for dislocation motion, thus influencing the solid solution hardening and softening in aluminum, which ...

A Simulative Approach for the Prediction of Mesoscale Residual Stress Fields in Solution‐Strengthened Ferritic Ductile Iron

open access: yesAdvanced 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 ...

Computing the numerical radius

open access: yesLinear Algebra and its Applications, 1996
The paper deals with the numerical calculation of the numerical radius of a complex matrix. The derived methods consist mainly of matrix-vector multiplications, being based on the power method for calculating the largest eigenvalue (in modulus) of a Hermitian matrix. Computational tests are given to show the efficiency of the proposed algorithm.

On tubes of nonconstant radius [PDF]

open access: yesTsukuba Journal of Mathematics, 1993
Tubes about submanifolds play an important role in Riemannian geometry and their properties have been studied intensively and applied on many occasions. For example, we refer to [\textit{A. Gray}, Tubes, Addison- Wesley, Redwood (1990; Zbl 0692.53001)] and [the reviewer, Rend. Semin. Fac. Sci., Univ. Cagliari, supplemento al vol.
