Roark's Formulas for Stress and Strain is a mechanical engineering design book written by Richard G. Budynas and Ali M. Sadegh. It was first published in 1938 and the most current ninth edition was published in March 2020.

Subjects

The book covers various subjects, including bearing and shear stress, experimental stress analysis, stress concentrations, material behavior, and stress and strain measurement. It also features expanded tables and cases, improved notations and figures within the tables, consistent table and equation numbering, and verification of correction factors. The formulas are organized into tables in a hierarchical format: chapter, table, case, subcase, and each case and subcase is accompanied by diagrams.

The main topics of the book include:

• The behavior of bodies under stress

• Analytical, numerical, and experimental methods

• Tension, compression, shear, and combined stress

• Beams and curved beams

• Torsion, flat plates, and columns

• Shells of revolution, pressure vessels, and pipes

• Bodies under direct pressure and shear stress

• Elastic stability

• Dynamic and temperature stresses

• Stress concentration

• Fatigue and fracture

• Stresses in fasteners and joints

• Composite materials and solid biomechanics
