Optimum Design of Infinite Perforated Orthotropic and Isotropic Plates

Mathematics, 2020
In this study, an attempt was made to introduce the optimal values of effective parameters on the stress distribution around a circular/elliptical/quasi-square cutout in the perforated orthotropic plate under in-plane loadings.

Analysis of Elastic–Plastic Problems Using the Improved Interpolating Complex Variable Element Free Galerkin Method

Mathematics, 2021
A numerical model for the two-dimensional nonlinear elastic–plastic problem is proposed based on the improved interpolating complex variable element free Galerkin (IICVEFG) method and the incremental tangent stiffness matrix method.

A simple pooling method for variable selection in multiply imputed datasets outperformed complex methods

BMC Medical Research Methodology, 2022
Background For the development of prognostic models, after multiple imputation, variable selection is advised to be applied from the pooled model. The aim of this study is to evaluate by using a simulation study and practical data example the performance

Research on Vibration Suppression of Nonlinear Tuned Mass Damper System Based on Complex Variable Average Method

Buildings, 2023
Tuned mass dampers (TMDs) are widely used as vibration damping devices in engineering practice. However, during use, TMDs inevitably exhibit some nonlinear characteristics that may negatively impact engineering applications.

Toolpath dependent stability lobes for the milling of thin-walled parts [PDF]

, 2008
The milling of thin-walled parts can become a seriously complex problem because the parts have variable dynamics. Firstly, the dynamics evolution of the part has been calculated through Finite Element Method (FEM) analysis.

Optimal thermal design of anisotropic plates with arbitrary cutouts using genetic algorithm

Theoretical and Applied Mechanics Letters, 2022
Anisotropic plates in different applications may have geometric defects such as openings and cracks. The presence of the opening disturbs the heat flow, which creates significant thermal stress around the opening. When the heat flux is high enough, these

Temperature Accelerated Monte Carlo (TAMC): a method for sampling the free energy surface of non-analytical collective variables [PDF]

, 2011
We introduce a new method to simulate the physics of rare events. The method, an extension of the Temperature Accelerated Molecular Dynamics, comes in use when the collective variables introduced to characterize the rare events are either non-analytical ...
