| Popis: | Publisher Summary This chapter discusses the mechanics of solids. The most common form of stress analysis used in engineering deals with material behavior that is said to be linear elastic, hence, conforming to Hooke's law, which states that strain is linearly proportional to stress. A stress wave passes through a material when the different sections are not in equilibrium, as in the case of colliding bodies. Because of the material properties of a body, a finite time is required for this disequilibrium to be felt by other parts of the body. The lack of load equilibrium is observed by the presence of stress waves moving through a particular section. The behavior of materials beyond the level of strain whereby there is no longer a linear relationship between stress and strain is called “plasticity.” In dealing with stress systems beyond the elastic limit, similar to those associated with metal forming, the engineer's definition of stress and strain becomes obsolete and stress and strain are defined with respect to the current deformed states. |
