Engineering materials and their applications
This edition of the classic text/reference book has been updated and revised to provide balanced coverage of metals, ceramics, polymers and composites. The first five chapters assess the different structures of metals, ceramics and polymers and how stress and temperature affect them. Demonstrates how to optimize a material's structure by using equilibrium data (phase diagrams) and nonequilibrium conditions, especially precipitation hardening. Discusses the structures, characteristics and applications of the important materials in each field. Considers topics common to all materials—corrosion and oxidation, failure analysis, processing of electrical and magnetic materials, materials selection and specification. Contains special chapters on advanced and large volume engineering materials plus abundant examples and problems.

Now that we have described the nature of metal structures, let us note the effects
of stress and temperature on them. These effects are important for two reasons. 1.
To form parts into the required shape and to obtain the desired properties, we ...
Determine the stress, the elastic and plastic components ot strain, and the bar
length when under load. ANSWER Stress =*^ = i,35-00°'b = 70,000 psi (483 MPa
) area 1 in. x 0.5 in. At this stress the total strain is 0.010 in./in. (Example 3.2).
Elastic strain The elastic displacement of atoms from their normal positions, as for
example by applying a tensile or compressive stress. When the stress is removed
, the atoms return to the normal spacing. Engineering strain, e Change in ...
