Full Description
This respected handbook introduces the entire spectrum of mechanical behavior of materials, emphasizing practical engineering methods for testing structural materials to obtain their properties, and predicting their strength and life when used for machines, vehicles, and structures. KEY TOPICS: Features expanded discussions of safety factors, stress and strain, bending and torsion tests, unknown fiber fraction, 3-D stresses, and modified-Mohr and Coulomb-Mohr criteria. Also addresses maximum shear and octahedral shear criteria, load factor design, fatigue limits, notch sensitivity, R-ratio effects, mean stress relaxation, cyclic bending, mean stresses, and time-temperature parameters. Coverage of fracture mechanics allows readers to analyze the effect of cracks on strength and life without requiring advanced mathematics. Employs actual laboratory data in illustrations, examples, and problems, giving readers realistic impressions as to the actual values and behavior for the material involved. A useful reference for practicing engineers.
