The book introduces Hooke, Young, and Poisson and follows their adventures as they push all sorts of matters beyond the yield point, towards the ultimate limit.
The shear stress of reading about fractures and dislocations may be a bit overwhelming, but if you take an isotropic view of the world, you realize that at the end of the day, if you stay inside the elastic limit, everything comes back to where it is supposed to.
Roark's Formulas for Stress & Strain is an engineering classic that is a must-have resource for any engineer specializing in strength & structures. It is especially useful for folks with this specialty in the aerospace, mechanical or civil disciplines.
It provides simple formulas to analyze a wide range of simple structural elements including straight and curved beams, plates, shells, and the like. Usage of these simple formulas allows an analyst to make quick hand-analysis solutions to a wide number of problems by using solid judgement to idealize the structures in a simplifying manner. Practice using these techniques and comparison of the results to all "higher" forms of analysis enables an engineer to hone, refine and develop their judgement.
While the newer versions of this text like the subject one that was edited & updated by Young lend themselves to programmed computing and open the door to a wider range of problems, this "benefit" comes at the cost of increased complexity and convolution of the formulas. Therefore, it can be insightful and sometimes preferable to find an older edition by the original author Roark, which may have narrower scope but which utilizes simpler forms for many of the equations.
Either way, this text is worth the cost for any engineer serious about structural analysis.
Easily my favorite engineering reference book. Particularly when it comes to looking up the odd formula that you memorized for an exam, then promptly forgot.
This book is the definitive starting point when it comes to analyzing stresses and strains in new applications. It's the first book I turn to for figuring out applications, and it's my go to when remembering even simple plate and beam equations.
