Advanced Engineering Materials, EarlyView.Cladding is a proven method that boosts the surface qualities of mechanical parts by applying a layer of more durable material over a base substrate. This work responds to the needs of offshore and pressure vessels sectors by focusing on cladding a super austenitic steel onto low‐carbon steel through gas tungsten arc welding.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Square matrices with the inverse diagonal property
Kuwait Journal of ScienceWe identify the class of real square invertible matrices A for which the signs of the diagonal entries of A−1 match those of A, and begin their study. We say such matrices have the inverse diagonal property (IDP).

Numerical Exploration of Thermal Shock Resistance in MgO–C Refractories
Advanced Engineering Materials, EarlyView.A mesostructure‐resolved numerical framework is developed to evaluate the thermal shock resistance of MgO–C refractories. By modeling interface debonding under rapid temperature changes and introducing a modified thermal shock parameter that accounts for mesocracks, the study shows how graphite content and aggregate size influence thermal shock ...

About gauge equivalent of the generalized Landau-Lifshitz equation
Вестник КазНУ. Серия математика, механика, информатика, 2017 In mathematics an inverse scattering transformation is a method for solving some nonlinear equations with partial derivatives. Discovering of the method became one of the crucial events in mathematical physics in the last 40 years [1]–[6].

The Reverse Order Law for the {1,3M,4N}—The Inverse of Two Matrix Products
AxiomsBy using the maximal and minimal ranks of some generalized Schur complement, the equivalent conditions for the reverse order law (AB){1,3M,4K}=B{1,3N,4K}A{1,3M,4N} are presented.

On an inequality for the Hadamard product of an M-matrix and its inverse
Linear Algebra and its Applications, 2000 Let \(A=[a_{jk}]\) be an \(n\times n\) \(M\)-matrix whose inverse is doubly stochastic. Then \[ q(A\circ A^{-1})\geq 2\max a_{kk}/(n \max a_{kk}-n+1), \] where \(\circ\) denotes the Hadamard product, \(q(B)=1/p(B^{-1})\) and \(p(C)\) is the Perron eigenvalue of a nonnegative matrix \(C\).
