In recent years, the prediction of the effective transport properties have received a great number of investigations. The present work is dedicated to determining the effective permeability of two-dimensional (2D) doubly porous materials made of an isotropic permeable solid matrix in which elliptical shaped pores of any size are embedded. At the interface between the fluid and the solid, the Beaver–Joseph–Saffman conditions are applied.

In this article, we introduce a method for synchronizing operations from 2D digital mapping software to 3D digital sand table software using AI technology. This method solves the challenges and difficulties of combining 2D and 3D in military applications, such as the difference between 2D and 3D space, the accuracy and efficiency of the synchronization process, and the user experience when working with three-dimensional space.

In this study, we propose to build an equivalent 2D model to replace the 3D model of corrugated composite sheets, by the method of homogenization, to study the nonlinear mechanical behavior of corrugated core composite sheets. This model helps to significantly reduce the calculation time as well as the model building time. The model homogeneity is confirmed by comparing the numerical simulation results of the 2D model and the 3D model.

In this paper, the free vibration of a bi-directional functionally graded (2D-FG) nanobeams is investigated by the finite element method. Nanobeams are made of two kinds of porous materials. The material properties of 2D-FG nanobeams are assumed to vary in both axial and thickness directions according to a power law . Based on Eringen's nonlocal elasticity theory, the governing equations of motion are derived.

In the present paper, a 2D nonlinear beam element based on the geometrically exact formulation for large displacement theory of beams developed by Zienkiewicz [7] is formulated on the basis of the first-order shear deformation theory and the total Lagrangian method. The displacements of the element are described through the original (reference) configuration.

In the paper "Finite element analysis for the composite sandwich plate using the homogenization method", we propose a homogeneous model for the composite sandwich plate. Accordingly, the 3D plate model will be replaced by a 2D homogeneous panel. Analytical calculations were performed for both models. The proposed model is confirmed by comparing the results obtained with the 3D plate model. The findings of this research will help us continue to build and finalize a homogenous model for a variety of structures.

The eXtended Finite Element Method (XFEM) produces high effectiveness in analyzing the crack propagation in structures. In this approach, the crack is modeled through enrichment functions instead of explicitly represented on the geometry. This study presents an object-oriented program to simulate crack propagation in 2-dimensional structures.

Ebook "Multi-shell polyhedral clusters" presents new methodologies and rationalizes existing methods that are used in the design of multi-shell polyhedral clusters. The author describes how the methods used are extended from 2D-operations on maps to 3D (and higher dimensional) Euclidean space. A variety of structures is designed and described in detail and classified giving rise to an atlas of multi-shell nanostructures. The book therefore sheds a new light on the field of crystal and quasicrystal structures, an important part of nanoscience and nanotechnology.

This enables the use of straightforward methods for isogeometric analysis in conventional finite element systems. A SOCP problem is created from the limit analysis problem, which may then be solved using Mosek optimization software. The numerical results indicate the correctness and effectiveness of the current technique by contrasting it with other approaches mentioned in the literature.

This paper presents the results of determining the coefficient of friction when cold plastic deformation by the method of cold ring upsetting with different lubricants. The ring upsetting process is performed with varying degrees of deformation with three lubricants used: industrial oil, cooking oil, and zinc sulfate powder. Based on the deformation and dimension change of the samples after the upsetting, the coefficient of friction was determined by correlation comparison with the friction calibration curve performed by Male and Cockcroft.
