Visualization of Constitutive Relations and Stress and Strain Tensors in Mechanics (VIZCORE)

详细技术说明

In this technology, advanced constitutive relations are used in engineering mechanics to simulate measured material behavior in the laboratory, and in analytical models (finite elements/difference). The software transforms the representation of constitutive relations, as well as stress and strain quantities from a series of mathematical equations and matrix quantities to multidimensional geometric/visual objects in a dynamic, interactive display environment.

*Abstract

In this technology, advanced constitutive relations are used in engineering mechanics to simulate measured material behavior in the laboratory, and in analytical models (finite elements/difference). The software transforms the representation of constitutive relations, as well as stress and strain quantities from a series of mathematical equations and matrix quantities to multidimensional geometric/visual objects in a dynamic, interactive display environment. 

DESCRIPTION/DETAILS 

This technology represents a new approach to the development, evaluation, and use of material constitutive models and similar stress-strain relationships used in analytical models. The software introduces a novel interactive visualization development and learning environment for material constitutive relations referred to as VizCoRe. VizCoRe:

• is a software workbench to represent constitutive relations and the implied material behavior that will transform complex mathematical formulations into visual renderings that are easily understood and manipulated. 
• introduces advanced renderings of three-dimensional states of stress and strain using glyph and hyper-streamline display techniques. This is a novel implementation of these techniques for representing constitutive models and related stress-strain states. 
• integrates and links computed material response in analytical models with the underlying fundamental constitutive behavior at the element level. 
• includes new routines to systematical probe material constitutive models. 
• includes new representation of material stiffness in three dimensions 
• is an internet-based computer platform that is independent and easily used on a desktop computer system. 

The software can also be packaged as a standalone applicationThis software provides users of analysis codes an easy way to examine material response at a point and relate it to the assumed constitutive behavior. It allow the user to enter laboratory data and data from numerical analysis and to plug-in their own constitutive model. The software also incorporates concepts of virtual reality to allow the user to "walk" through the constitutive relations. A force feedback capability can be added to allow the user to "feel" a stress or stain. A sound component can be added to allow the user to hear the stress and strain.

APPLICATIONS 

The software is designed to be a stand-alone product that could be used over the Internet, but it could also be packaged as an add-on to existing software. It has capability to import data output from large scale finite element/finite difference analysis codes. The computer-aided engineering (CAE) industry, including: 

• Aerospace 
• Automotive 
• Mechanical 
• Engineering 
• Biomedical 
• Engineering 
• Civil Engineering 

BENEFITS 

• Better with visualization: This software adds novel methods for dealing with constitutive relations and stress that makes it easier to use and understand via its graphical interface. 
• Easier & cheaper: Takes advantage of current advancements made in information technology and computer graphics to make interpretation of numerical analysis results more cost-effective and easier to use.
