Abstract:

As a new type of composite material, particle reinforced composite materials, which has good mechanical properties and secondary machining, have been widely used in mechanical, biological, aerospace, military, motor and other important industrial areas. With the development of science and technology lots of research and numerical simulation have been carried on at home and aboard. Because of the reinforcements, the overall mechanical properties have been significantly improved. At the same time, fracture properties and fatigue characteristics are lower. This paper, based on the VCFEM, lead in

Abstract:

This paper bases on the principle of the stress hybrid element, using voronoi cell finite element method to analysis the interfacial debonding phenomenon of a particle reinforced composite materials, then it contrasts by the commercial finite element software MARC in the same conditions of numerical simulation. Research results show that: In the interfacial debonding, especially at the crack tip stress, Stress is the biggest. Particles and matrix interface delamination is the important cause of material damage, at the same time, it has a great impact on the service life of components.

Abstract:

A simulation method of macro-and meso-scales is developed for particle reinforce composite materials. The two-scale modeling based on homogenization theory enables to formulate the macro scale problem with Finite Element Method (FEM), while the meso-scale one with Voronoi Cell Finite Element Method (VCFEM). Dangerous regions are identified in macro scale computing period, which lately be meshed into Voronoi Cells in meso-scale period to get a more accurate solution. Representative numerical examples are presented to demonstrate the capability of the proposed two-scale analysis method of partic

Abstract:

A varying cell-size method based on Voronoi technique is extended to construct 3D graded cellular models. The dynamic behaviors of graded cellular structures with different density gradients are then investigated with finite element code ABAQUS/Explicit. Results show that graded cellular materials have better performance as energy absorbers. Graded cellular structures with large density near the distal end can protect strikers, and those with low density near the distal end can protect structures at the distal end. It is concluded that graded cellular materials with suitable design may have ex

Abstract:

The modeling of problems where the boundary changes significantly over time may become challenging as the mesh needs to be adapted constantly. In this context, computational methods where the mesh does not conform to the boundary are of great interest. This paper proposes a stabilized cut-cell approach to solve partial differential equations using unfitted meshes using the Finite Element Method. The open-source library deal.ii was used for implementation. In order to evaluate the method, three problems in two-dimensions were tested: the Poisson problem, a pure diffusion Laplace-Beltrami proble

Abstract:

Concrete is a popular construction material for bridges, due to its high durability and energy efficiency. An important concern for concrete bridges is the possible occurrence of chloride- induced corrosion in prestressing strands and reinforcing bars, which may substantially impact the service life of such structures. Chloride- induced corrosion is a complicated electrochemical process which is affected by heat transfer, moisture flow and transport of chemical species through the concrete pore network. Reliable and robust analytical tools are required to allow multi-physics simulations of ste

Abstract:

This paper provides two separate methodologies for implementing the Voronoi Cell Finite Element Method (VCFEM) in topological optimization. Both exploit two characteristics of VCFEM. The first approach utilizes the property that a hole or inclusion can be placed in the element: the design variables for the topology optimization are sizes of the hole. In the second approach, we note that VCFEM may mesh the design domain as n sided polygons. We restrict our attention to hexagonal meshes of the domain while applying Solid Isotropic Material Penalization (SIMP) material model. Researchers have sho

Background: Although trabecular bone is highly porous heterogeneous composite, most studies use homogenized continuum finite element (FE) approaches to model trabecular bone.

The purpose of this study is to demonstrate an approach that simulates trabecular bone with less dependency on medical images while capturing of porosity.

Three-dimensional structure of trabecular bone can be modeled by 2D or 3D Voronoi structure. The effect of missing cell walls on the mechanical properties of 2D honeycombs is a first step towards understanding the effect of local bone resorption due to osteoporosis. In patients with osteoporosis, bone mass is lost first by thinning and then by resorption of the trabeculae [1]. Furthermore, creep response is important to analyze in cellular solids when the temperature is high relative to the melting temperature. For trabecular bone, as body temperature (38 °C) is close to the denaturation tempe
