I thought that your readership might be interested in a textbook that I recently published entitled "Soft Solids: A primer the the mechanics of materials." It is geared for the senior-masters level student.

Chapters include: motion, deformation, strain, stress, explicit elasticity, implicit elasticity, and viscoelasticity.  Four appendices address: linear algebra review, covariant and contravariant field transfer, Kronecker products, and an inherent Runge-Kutta stable integrator.
