The Mathematical Theories of the Inelastic Continuum
This article is an attempt to present the current stage of development of the theories of the inelastic continuum. In contrast to the classical theories of elasticity and hydrodynamics, the present status of w...

Chapter
Fracture
In 1776 Coulomb [1] expressed the view that fracture of a solid would occur if the maximum shear strain at some point surpassed a critical value characterizing the mechanical strength of the material. Although th...

Chapter
Photoelasticity
When loads are applied to any solid body the stresses induced in the body vary, in general, from point to point, and there will be regions of high stress which will constitute the weak points of the body at wh...

Chapter
Rheology
Although the word “rheology” is derived from the Greek “ϱεω”, which means “flow”, it is used in the wider sense to mean that branch of physics which is concerned with the deformation of materials.

Chapter
Fatigue
Fracture produced by a monotonically increasing force represents the terminal point of a process of inelastic deformation at which the rate of such deformation is no longer sufficient to prevent the rapid spre...

Chapter
The Classical Theory of Elasticity
The theory of elasticity is concerned with the mechanics of deformable bodies which recover their original shape upon the removal of the forces causing the deformation. The first discussions of elastic phenome...

Some of the Laws Governing Mechanical and Thermal Strength
Until recently, effects of mechanical loads (such as weight), inertia, the pressure of solids, liquids, gases, etc., have received most of the attention in studies of strength of materials and structural eleme...

Chapter
Thermal Fatigue and Thermal Shock
Problems in the strength of structural materials in a variable temperature field are attracting more and more attention from engineers, as well as from investigators working in the most diverse branches of tec...

Chapter
Thermal Stability of Plates and Shells
The demands of many modern branches of engineering are such that questions dealing with loss of stability of structural elements at elevated temperatures have recently begun to attract the attention of large g...

Thermal Stresses and their Calculation
Thermal (or temperature) stresses are a variety of internal (inherent) stress. This name, as we know, is given to stresses that are in equilibrium in a given body (or part of it, or in a system of several bodi...

Fundamentals of Creep Calculations on Nonumiformly Heated Parts
The development of engineering in recent years has been toward using higher and higher temperatures in power plants. Here, in addition to using heat-resistant materials, intense cooling of hot assemblies must ...

Chapter
Introduction
It is difficult to define the term “refractory compound,” since any subdivision into refractory and nonrefractory compounds is arbitrary and presupposes the fixing of some melting point boundary above which ch...
