Theoretical study and numerical analysis of continuum mechanics

1. “断裂现象的理论研究与数值分析”研讨会举办了三次，为期三年（1998-2000），每次研讨会约有30名参与者和12名演讲者。他们的旅费和住宿费由本研究基金资助。在这个研讨会上，数学家和断裂力学的理论研究人员在有趣的讲座后，就断裂现象进行了讨论。第一次讲习班于1995年1月27日至29日举行，最近一次讲习班是2000年11月10日至12日举行的第6次讲习班。申请人是巴黎大学的pironneau教授领导的FreeFem+项目的成员。另一位成员是Frederic Hecht，他在网站“http://www.rocq.inria.fr /Frederic.Hecht/FreeFemPlus.htm”上发布了FreeFem+。我的主要部分是MS-Windows版FreeFem+的用户界面。现在我在FreeFem+中制作可视化工具“vffem”，显示水平线，带阴影的三维图形，线框等。本软件采用OpenGL （GLUT）语言和c++语言编写而成。我将在不久的将来出版“vffem”。

1. The workshop "Theoretical research and numerical analysis on fracture phenomena" was held three times for three years (1998-2000) with about 30 participants and 12 speakers in each workshop. Their travel expenses and lodging charges are supported by this research funds. In this workshop, mathematicians and theoretical researchers on fracture mechanics joined and discussed each other on fracture phenomena after interesting lectures. The first workshop was held in 27-29 Jan.1995 and the recent workshop was 6th in 10-12 Nov.2000.2. The applicant have been the member of FreeFem+ project whose leader is Prof.Pironneau belonging to Paris University 6. Another member is Frederic Hecht in Paris VI.We publish FreeFem+ in the site "http : //www-rocq.inria.fr/Frederic.Hecht/FreeFemPlus.htm". My main part is the user interface for MS-Windows version of FreeFem+. Now I making the visualization tool "vffem" for FreeFem+ that shows the level lines, 3 dimensional graph with shading, wire frame etc. This software has been constructed by OpenGL (GLUT) and using C++. I will publish "vffem" in near future.
