Continuum Mechanics in Maxima Computer Algebra System

cont_mech is a Maxima package intended to aid with operative issues in Continuum Mechanics lecturing and research. I wrote this package when I was lecturing the undergrad course Mecánica de los Medios Continuos (Introduction to Continuum Mechanics) for Civil Engineering at Universidad EAFIT.

The package was mainly created for two reasons:

1. Help a student with reduced mobility to solve exercises in the computer (he could use it). So, it also helped me with the evaluation: making tests that can be solved in a computer.
2. Make some tedious calculations like vector identities, or apply differential operators in elasticity.
