9984125This Faculty Early Career Development (CAREER) research and education project addresses a novel interactive visualization development and learning environment for material constitutive relations, referred to as VizCoRe.Advances in computer and information technology permit engineers to use numerical simulations on a routine basis to support their design work. In geotechnical engineering, numerical simulations are used to study the complex response of soil and rock in urban areas to construction activities. These simulations depend upon the accurate representation of the load-deformation material response of the ground in the form of constitutive equations; concepts that traditionally have been difficult to understand, develop and use, except by a few specialists.This project initiates a fundamental shift in the current approach by taking advantage of rapid advancements in information technology and computer graphics. It transforms the representation of constitutive relations, as well as stress and strain quantities, from a series of mathematical equations and matrix quantities into multidimensional geometric/visual objects in a dynamic interactive color-rich display environment. Complex mathematical formulations are transformed into visual renderings that are easily understood and manipulated. This environment is being developed as a software workbench that is Internet based, computer platform independent, and easily used on a desktop computer system. It allows multiple users to view and study models in a collaborative environment.It is an inherently educational project, as it will greatly simplify the use of constitutive relations for both the expert and non-expert user. It can be used to teach a wide audience of students and practicing engineers about constitutive relations and their significance in numerical simulations, using a simple intuitive approach. Its availability on the World Wide Web, and its multi-user features, fosters a collaborative learning environment amongst students and engineers. The project involves collaboration with the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign.

9984125本学院早期职业发展（CAREER）研究和教育项目解决了一种新的交互式可视化开发和学习环境的材料本构关系，被称为VizCore.Advances在计算机和信息技术允许工程师使用数值模拟在常规的基础上，以支持他们的设计工作。 在岩土工程中，数值模拟用于研究城市地区土壤和岩石对施工活动的复杂响应。 这些模拟取决于准确的表示的负荷变形材料的地面响应的形式的本构方程;概念，传统上一直难以理解，开发和使用，除了少数expertes.This项目启动了一个根本性的转变，在目前的方法，利用信息技术和计算机图形学的快速发展。 它将本构关系以及应力和应变量的表示从一系列数学方程和矩阵量转换为动态交互式色彩丰富的显示环境中的多维几何/视觉对象。 复杂的数学公式被转换成易于理解和操作的视觉效果图。 该环境被开发为基于因特网、独立于计算机平台并且易于在台式计算机系统上使用的软件工作台。 它允许多个用户在协作环境中查看和研究模型。它本质上是一个教育项目，因为它将大大简化专家和非专家用户对本构关系的使用。 它可以用来教广大的学生和实践工程师关于本构关系及其在数值模拟中的意义，使用一个简单的直观的方法。 它在万维网上的可用性及其多用户功能，在学生和工程师之间促进了协作学习环境。 该项目涉及与伊利诺伊大学厄巴纳-香槟分校的国家超级计算应用中心（NCSA）的合作。
