ABSTRACT In this paper, we propose a decompositional (phase‐wise split) approach to solve a two‐dimensional, two‐phase (solid and liquid, say), nonlinear inverse Stefan problem. The first step is to approximate the unknown moving boundary between the two phases and the Stefan condition on that boundary using the overspecified boundary and initial data ...

This study develops a superconvergent meshless method to analyze and control vibrations in twisted, bidirectional functionally graded Terfenol‐D beams. By optimizing magnetostrictive patch placement, it demonstrates effective vibration suppression under dynamic loads, highlighting the design potential of strategically graded materials in complex ...

Adaptive smoothed FEM for forming simulations [PDF]
FEMsimulation of large deformations as occur in metal forming processes is usually accompanied with highly distorted meshes. This leads first to a reduction of accuracy and later to loss of convergence when implicit solvers are used.

Meshless IEFGM‐Based Numerical Modeling of Grounding Systems With Counterpoise Wires
ABSTRACT This paper presents a comprehensive numerical analysis of a counterpoise grounding wire subjected to low‐frequency surge currents, employing the Interpolating Element‐Free Galerkin Method (IEFGM). The analysis involves significant challenges arising from the high ratio between the conductor length and its radius—which demands fine spatial ...

Support Structure Modelling in Actuator Line Method Large Eddy Simulations of Wind Turbine Wakes
ABSTRACT While advancements in the prediction of wind turbine loads and wakes within the actuator line method large eddy simulation (ALM‐LES) framework have been an active research topic in recent years, the modelling of the tower and nacelle has received comparatively less attention.

Meshless Methods for Large Deformation Elastodynamics
Meshless methods are a promising candidate to reliably simulate materials undergoing large deformations. Unlike mesh based methods like the FEM, meshless methods are not limited in the amount of deformation they can reproduce since there are no mesh regularity constraints to consider.
