Porous Elasticity

Written by: Dr. Ray M. Bowen (Texas A&M University)

The origins of this mechanical engineering textbook go back over 30 years. Dr. Ray M. Bowen was teaching Mechanical Engineering at Rice University. Since then, he has held a variety of positions at Oklahoma State University and Texas A&M University. For eight years, he was President of Texas A&M. This educator is offering his 10 chapter textbook to all students.

Unfortunately, there’s no mention of prerequisites or what specific course this text would generally be tied to. I can tell you, based upon glancing through it quickly, you are going to need a great deal of calculus prior to tackling this one. Bowen lists the subjects as: Porous, Elasticity, Mixtures and Continuum Mechanics. The complete title is Porous Elasticity, Lectures on the Elasticity of Porous Materials as An Application of the Theory of Mixtures.

The text was originally made available in 2008. The current 2014 version corrected some typos and included an index.
