PREFACE of Principles of Solid Mechanics by Rowland Richards:

There isn’t a space of utilized science extra numerous and highly effective than the mechanics of deformable solids nor one with a broader and richer historical past. From Galileo and Hooke by means of Coulomb, Maxwell, and Kelvin to von Neuman and Einstein, the query of how solids behave for structural purposes has been a fundamental theme for bodily analysis thrilling the very best minds for over 400 years.

From basic questions of solid-state physics and materials science to the mathematical modeling of instabilities and fracture, the mechanics of solids stays on the forefront of at the moment’s analysis.

On the identical time, new modern purposes comparable to composites, prestressing, silicone chips, and supplies with reminiscence seem in all places round us.

To current to a pupil such a beautiful, multifaceted, psychological jewel in a approach that maintains the thrill whereas not compromising magnificence and rigor, is a problem no instructor can resist.

It’s not too tough on the undergraduate degree the place, in a collection of programs, the coed sees that the straightforward options for bending, torsion, and axial load lead on to evaluation and design of all kinds of plane constructions, machine elements, buildings, dams, and bridges.

Nevertheless, it’s rather more tough to keep up this enthusiasm when, on the graduate degree, the following layer of sophistication is important to deal with all these conditions, heretofore glassed over and postponed, the place the strength-ofmaterials strategy could also be inaccurate or the place a real area idea is required instantly.

This guide has developed from over 30 years of educating superior seniors and first-term graduate college students a core course on the applying of the full-range area idea of deformable solids for evaluation and design.

It’s offered to assist academics meet the challenges of main college students of their thrilling discovery of the unifying area theories of elasticity and plasticity in a brand new period of highly effective machine computation for college kids with little experimental expertise and no publicity to drawing and graphic evaluation.

The intention is to focus on basic ideas, fundamental purposes, easy issues but unsolved, inverse methods for optimum design, unanswered questions, and unresolved paradoxes within the hope that the keenness of the previous may be recaptured and that our continued fascination with the topic is made contagious.

In its evolution this guide has, subsequently, grow to be fairly totally different from different texts overlaying basically the identical subject material at this degree.2 First, by together with plastic in addition to elastic conduct in phrases of a unified idea, this textual content is wider in scope and extra numerous in ideas.

I’ve discovered that college students wish to see the complete vary, nonlinear response of constructions and extra absolutely recognize the significance of their work once they notice that incompetence can result in sudden demise.

Furthermore, restrict evaluation by Galileo and Coulomb traditionally predates elastic options and can be turning into the popular technique of evaluation for design not solely in soil mechanics, the place it has at all times dominated, however now in most codes for concrete and metal constructions.

Thus within the ultimate chapters, the hyperbolic area equations of plasticity for a common Mohr-Coulomb materials and their resolution in closed type for particular circumstances is first offered.

The extra common case requiring slip-line idea for a proper plasticity resolution is then developed and utilized to the punch drawback and others for comparability with approximate upper-bound options.

Secondly, whereas the idea offered within the first three chapters covers acquainted floor, the emphasis in its growth is extra on visualization of the tensor invariants as impartial of coordinates and uncoupled within the stress–pressure relations.

The elastic rotations are included in anticipation of Chapter 4 the place they’re proven to be the harmonic conjugate operate to the primary invariant resulting in stream nets to explain the isotropic area and closed-form integration of the relative deformation tensor to find out the vector area of displacements.
