Osobliwe Równania Całkowe Termosprężystości
Engineering Transactions, 1965 The present paper contains a derivation of the integral representation of the general solution of coupled linear elasticity. It is assumed that the material and thermal constants are independent of the temperature and that the vibration is harmonic.

On the asymptotic convergence of the polynomial collocation method for singular integral equations and periodic pseudodifferential equations [PDF]
, 2002 summary:We prove the convergence of polynomial collocation method for periodic singular integral, pseudodifferential and the systems of pseudodifferential equations in Sobolev spaces $H^{s}$ via the equivalence between the collocation and modified ...

Advanced Engineering Materials, EarlyView.This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.

REGULARIZAREA ŞI SOLUŢIONAREA UNOR ECUAŢII INTEGRALE SINGULARE
Studia Universitatis Moldaviae: Stiinte Umanistice, 2010 In this study there are established relations between the solutions of singular integral equations and equations which are obtained as a result of their regularization and conditions that ensure equivalence of these equations.

An hp-version discontinuous Galerkin method for integro-differential equations of parabolic type
, 2011 We study the numerical solution of a class of parabolic integro-differential equations with weakly singular kernels. We use an $hp$-version discontinuous Galerkin (DG) method for the discretization in time.

Influence of Geometric Design on Mechanical Performance of Auxetic Metastructure
Advanced Engineering Materials, EarlyView.Strategic geometric reinforcement transforms auxetic performance. This study evaluates 3D‐printed arrowhead metastructures, revealing that a modified design with local ring reinforcement suppresses premature failure to achieve superior energy absorption and structural efficiency.
