连续介质力学简介

连续介质力学是近代物理学中的一个重要分支,它是以统一的观点来研究连续介质在外部作用下变形和运动规律的一门学科,是流体力学、粘弹性力学、塑性力学等众多力学的重要理论基础。 连续介质力学的基本方程有三类: (1) 关于物体变形和运动的几何学描述,它可具有任意要求的精度。 (2) 适用于一切连续介质的物理基本定律,如质量守恒定律、动量守恒定律等以及热力学定律。 (3) 描述材料力学性质的宏观本构关系。 以上三类基本方程,连同相应的初始条件和边界条件,构成数学物理方程的初、边值问题的完整提法。    Send article as PDF   

Learning, writing

Until now, I can’t open *.blogspot.com, but, however I write my blog. I found a good site www.answers.com today, which can give us answers almost about everything. I began to learn Continuum Mechanics, which is very dull. It has many maths fomulas, especially tensors calculus. I began to write my first article on my research, but I found it is… Read more →

Hope

Hope is everywhere. These days, I have been thinking about my research project. How large difference there is between theory and computation. Before yesterday, I only thought a little, but never practiced it, because I thought that the delta-distance and the delta-time are short enough. I computed it with computer by means of shortening the delta time yesterday. The result… Read more →

My blog is created

Today, I am very satisfied with Google's Blogger. So I create a blog to write something, e.g. my family, my research, my life, and etc. My blog page is chnrdu.blogspot.com on blogger.com.    Send article as PDF
