چکیده

We present a physically based method for visualizing deformation in particle simulations, such as those describing structural mechanics simulations. The method uses the deformation gradient tensor to transform carefully chosen glyphs representing each particle. The visualization approximates how simulated objects responding to applied forces might look in reality, allowing for a better understanding of material deformation, an important indicator of, for example, material failure. It can also help highlight possible errors and numerical deficiencies in the simulation itself, suggesting how simulations might be changed to yield more accurate results.

3D Microstructure Visualization of SiC Particle Reinforced Al Matrix Composites by X-Ray Synchrotron Tomography

Microstructural aspects of composites such as particle size, shape, and distribution play important roles in deformation behavior. 3D visualization of porosity and Fe-rich inclusions in three dimensions is critical to a thorough understanding of fatigue resistance of metal matrix composites (MMC) because cracks often initiate at these defects. In this paper we have used X-ray synchrotron tomogr...

New geometry for TCP: severe plastic deformation of tubes

Since tubes are widely used for different industrial applications, processing of tubes by the Severe Plastic Deformation (SPD) method has been the target of different attempts. Among these attempts, development of SPD processes for tubes based on Equal Channel Angular Pressing (ECAP) has been more successful. As an illustration, Tube Channel Pressing (TCP) has been presented as an attractive SP...

Particle-based Visualization of Soft-Tissue Deformation in the Human Orbit

Orbital fat is the soft tissue inside the eye socket, or orbit, that surrounds the eye muscles, eyeball, optic nerve and blood vessels. It plays an important role in the mechanical operation of the eye during eyeball rotation. Knowledge of how this orbital fat behaves is limited. It is important for surgeons to improve this knowledge to make better informed decisions before and during eye surge...

Particle Based Visualization of Stress Distribution Caused by the Aortic Valve Deformation

Medical and engineering technologies have developed the surgical simulators, which allow users to train for surgical skills. To perform the aortic valve replacement, which is one of the cardiovascular surgeries, it is necessary to examine not only the timing of the heart pulsating but also the stress distribution on the aortic valve. For pre-operative planning, we have visualized the stress on ...

Visualization of Smoothed Particle Hydrodynamics for Astrophysics

Scientific visualization still presents a number of challenges. Effective visualization straddles several problem domains the data structures needed to support visualization of large data sets, rendering techniques for fast and interactive display of this data, and enough understanding of the data involved to construct visualizations that provide real insight into the problem. Data from Smoothe...
