### Continuum Mechanics Website

www.continuummechanics.org is my sister website.
It covers all the fundamental aspects of mechanics - stress, strain,
principal values, Hooke's Law, von Mises Stress, etc - in the presence
of finite deformations and rotations.

This website presents the fundamental principles of fracture mechanics, with many examples included.
It covers both linear (LEFM) and nonlinear fracture mechanics, including J-Integrals,
as well as fatigue crack growth concepts and mechanisms.

I expect it to take several years to complete. In the meantime, I welcome
all input, suggestions, and contributions to improve its quality and usefulness.

for information on continuum mechanics. It covers all the fundamental aspects of
mechanics - stress, strain, principal values, Hooke's Law, von Mises Stress, etc
- in the presence of finite deformations and rotations.

### A Note About The Web Technologies Used Here

Two relatively new web technologies are used on these pages. The first is

Scalable Vector Graphics, or SVG.
Pages on this site will display SVG files in compatible browsers, and PNG files in incompatible ones.
The advantage of SVG over PNG is that SVG graphics can be scaled to any size without pixelization occurring.
SVG files used here were created using

Inkscape,
an excellent graphics program available free on the internet

here.

The second new technology used here is

MathJax, a Javascript based
display engine for mathematical equations programmed in the

LaTeX language.

MathJax eliminates the need to display equations as
GIF or PNG graphics files (or even SVG for that matter).

MathJax
requires only the following line of code in the <HEAD> segment of a web page.

```
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/latest.js?config=TeX-MML-AM_CHTML"></script>
```

It is then possible to program any math expression in the HTML source using the

LaTeX language.
For example, typing

`\(\sigma_{ij}\)`

produces \( \sigma_{ij} \).
