2D and 3D Numerical Analysis of Fluid Pressure Induced Fracture
Poromechanics V, 2013Simulation of 2D and 3D hydraulic fracturing in fully-saturated, porous media is presented. The discrete fracture/s is/are driven by the fluid pressure. A cohesive fracture model is adopted where, in the 3D case, the fracture follows the face of the element around the fracture tip which is closest to the normal direction of the maximum principal stress

Numerical analysis of bonding process-induced deformation for 3D package
2011 IEEE International 3D Systems Integration Conference (3DIC), 2011 IEEE International, 2012Three-dimensional integrated packaging has been generally acknowledged as the next generation semiconductor technology with the advantages of small form factor, high-performance, low power consumption, and high density integration [1,2]. Through silicon via (TSV) and stacked bonding are the core technologies to perform vertical interconnect for 3D ...

3D numerical back-analysis of an instrumented underpass road
World Journal of Engineering, 2020Purpose This paper aims to focus on three-dimensional (3D) numerical simulation of a monitored urban underground road consisting of diaphragm walls supported by one row of temporary steel struts and a cover slab in the central area. In addition to the lateral wall displacements, the analysis focuses on the load development in the struts and the ...

Numerical analysis of the interaction of 3D compressible bubble clusters
Applied Mathematics and Mechanics, 2019Based on the bubble dynamic theory and the compressible two-phase flow solver of the open source software OpenFOAM, a numerical simulation study is carried out on the interactions of bubble clusters in a closed volume. The bubble dynamics and interactions of a single bubble, two bubbles, and four bubbles are investigated under the working conditions ...

Back-Analysis of a Failed Rock Wedge Using a 3D Numerical Model
2015In the present paper, a rock wedge failure that occurred in the Rosandra valley (Trieste, NE Italy) has been back-analysed to compare the results of a traditional rock wedge analysis with those obtained using a 3D finite difference model (FDM). The simulations performed considering a purely frictional model of the rock wedge show that the values of the

Numerical analysis of parameter sensitivity in 3D TTI tomography
72nd EAGE Conference and Exhibition - Workshops and Fieldtrips, 2010We investigate the resolution of anisotropic model parameters in ray-based TTI reflection tomography. Our approach is to perform numerical experiments using 3D acoustic TTI finitedifference model data. In the first part of this presentation, we introduce a 3D TTI model that is used for this study.

3D DATA ACQUISITION AND NUMERICAL ANALYSIS OF A FOOTWEAR IN WALKING
2004The aim of the paper is to set a procedure to study the load history of a footwear during a step with non-linear FE analysis. The geometric model tested was reconstructed from a real shoe by means of Reverse Engineering process, starting from dense point clouds acquired by non-contact scanning system. For each phase of the walk, the pressure values are

Macroscopic properties of woven fabric composited by 3d numerical analysis
2000The mechanical properties of woven fabric composites could be predicted by two different approaches (1). The first is based on the lamination theory (see e.g. (2)) and is usually employed for approximated predictions of thermo-mechanical characteristics. The second gathers numerical refined finite element models (see e.g. (3)). In this work an approach

Numerical analysis of 3D multilayered cloaking in static fields
2017 Progress In Electromagnetics Research Symposium - Spring (PIERS), 2017This study is devoted to the numerical design of three-dimensional cloaking shell in static fields. The shell consists of a finite number of homogeneous layers. We need to find suitable properties of the layers in order to cloak a material body within the shell. This problem is formulated as the optimization problem where the physical parameters of the
