Free-form deformations are widely used to model 3D objects. In these methods “free-form” designates: “whatever the object is, whatever its description and topology, we are able to deform it”. They limit the user interaction to pull some points of an embedding rough mesh. From the user point-of-view, it does not matter if the object manipulated is 3-dimensional, of 0-genus or a parametric surfac...

تغییر شکل پلاستیک شدید یکی از مؤثرترین روش‌هایی است که طی آن می‌توان کرنش پلاستیک نسبتاً زیادی به نمونه فلزی اعمال نمود. از جمله مهم‎ترین روش‎های تغییر شکل پلاستیک شدید ورق‎ها می‎توان به فشرده‌سازی شیاری محدود و موج‎‎دار و صاف کردن متوالی اشاره کرد. این دو روش از نقطه نظر سیکل انجام فرآیند دارای شباهت‌هایی هستند، اما از نظر مقدار کرنش اعمالی متفاوت‌اند. لذا بررسی نحوه تغییر شکل اعمالی به نمونه ف...

Computer generated 3D forms using generative procedures have matured in the last decade and now considered as a tangible approach for realizing architectural design ideas. As fascinating as the approach might be, it is still lacking actual application in the early architectural design process. There are many reasons for this, among them: it has many implications over the architectural design pr...

BACKGROUND Three-dimensional (3D) bone shapes need to be created for visualization and pre-operative surgery planning. Conventionally such shape data is extracted from volumetric data sets, obtained by three-dimensional sensors, such as computerized tomography (CT) and magnetic resonance imaging (MRI). This conventional method is highly labor intensive and time consuming. METHODS This paper p...

This article presents the results of studying temperature distribution in process thermo-frictional cutting titanium alloy Ti-5553. The was simulated using Machining module DEFORM 3D software package based on finite element method. It found that when off Ti-5553, depending geometry circular saw, "disk-workpiece" contact zone reached T = 800 ÷ 1130 °C, and its propagation into depth workpiece 0....

BACKGROUND Medical image analysis in clinical practice is commonly carried out on 2D image data, without fully exploiting the detailed 3D anatomical information that is provided by modern non-invasive medical imaging techniques. In this paper, a statistical shape analysis method is presented, which enables the extraction of 3D anatomical shape features from cardiovascular magnetic resonance (CM...

An imaging-based computational framework for simulation of airflow in subject specific breathing human lungs is established. The three-dimensional (3D) airways of up to 9 generations and lobes are segmented and reconstructed from computed tomography (CT) images. Beyond the CT-resolved 3D airways, a volume filling method is applied to generate the one-dimensional (1D) conducting airway tree that...

This paper introduces a new method to stylize 3D geometry. The key observation is that the surface normal an effective instrument capture different geometric styles. Centered around this observation, we cast stylization as shape analogy problem, where relationship defined on normal. formulation can deform into styles within single framework. One plug-and-play target by providing exemplar or ene...

In this paper, an axle sleeve is formed through a combined cross wedge rolling (CWR) and hot extrusion process, the forming process simulated via finite element analysis software Deform-3D. The mechanism revealed by analyzing stress strain distribution, temperature variation metal flow law of workpiece during CWR extrusion. Combined with experiments, feasibility to produce verified. It has been...
