Engineering Reports, Volume 8, Issue 9, September 2026.Power System Contingency Analysis Procedure ABSTRACT In power system operation, contingency analysis (CA) is the systematic, proactive evaluation of credible, predefined events (such as the unplanned outage of a transmission line) to assess their potential impact on system security and reliability before they occur.

Applied Element Modelling of Out‐Of‐Plane Instability in Boundary Elements of Thin RC Walls
Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2800-2817, September 2026.ABSTRACT Recent earthquakes in Chile (2010) and New Zealand (2011) caused extensive damage to buildings featuring reinforced concrete (RC) structural walls, with observed failure modes including out‐of‐plane instability of slender walls. This buckling‐type response under combined in‐plane and out‐of‐plane loading has also been documented in ...

Tangent modulus in numerical integration of constitutive relations and its influence on convergence of N-R method [PDF]
Applied and Computational Mechanics, 2009 For the numerical solution of elasto-plastic problems with use of Newton-Raphson method in global equilibrium equation it is necessary to determine the tangent modulus in each integration point. To reach the parabolic convergence of Newton-Raphson method

Petri Nets for Automatic Wave Digital Code Generation
International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, Volume 39, Issue 5, September/October 2026.ABSTRACT Wave Digital (WD) models are a well‐established framework for the emulation of linear and nonlinear circuits. In practice, however, WD models are still implemented largely manually or through limited automated toolchains. Manual programming of WD models is time‐consuming and error‐prone for larger systems with pronounced algebraic dependencies,

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 13, Page 5185-5212, September 2026.ABSTRACT This study proposes a novel geometrically regularized gradient‐damage model for simulating dynamic mixed‐mode fracture in orthotropic materials with tension–compression asymmetry. In this model, a thermodynamic framework is formulated by incorporating damage dissipation into internal energy evolution, from which the constitutive relation and ...

steel research international, Volume 97, Issue 9, Page 4483-4493, September 2026.An accurate moving boundary model for volume diffusion containing boundary conditions from trans‐interface diffusion (TID) simulates the austenite growth during cooling. TID of Cr, Mo, N and Ni enhance growth kinetics. Without TID, compositions of the interface region change, decreasing the driving force for growth and finally causing numerical ...

International Journal for Numerical Methods in Engineering, Volume 127, Issue 16, 30 August 2026.ABSTRACT Large deformations can become an important issue in induction heating applications, especially for structures with low bending stiffness, such as thin sheets. In such cases, thermal expansion induces not only substantial in‐plane stresses but also out‐of‐plane buckling, which in turn strongly influences the electromagnetic field configuration.
