Meshless analysis of geometrically nonlinear beams

Journal of Physics: Conference Series, 2008
The meshless method is applied to the response analysis of a geometrically nonlinear beam. The corresponding nonlinear strain operator matrix and tangent rigidity matrix are given. The computational results agree well with Holden's analytic solution. It is found that the meshless method is more efficient for large displacement.

A Decompositional Approach for Two‐Dimensional, Two‐Phase, Nonlinear Inverse Stefan Problems Using the Method of Fundamental Solutions

Studies in Applied Mathematics, Volume 156, Issue 2, February 2026.
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 ...
