Abstract
The progress of technology finds us, today, confronted with an ever-increasing
number of technical problems. The automobile, the fast train, the airplane, and
a wide variety of high speed machines all require the solution of numerous problems
in stress analysis. Among the most important of these problems are those
concerned with impact stresses. Impact stresses are commonly assumed to be those stresses which are applied
instantaneously, as by a dropping weight, a sudden jerk on a cable and the like.
Quantitatively this is a vague definition indeed, but at present so little is
knov/n regarding the effect of the rate of application of load and the rate of
propagation of the stresses that for the present at least it will be retained. Their importance in the design of a structure can easily be seen, A given
structure or machine member may be perfectly safe for a certain load, if that
load is applied gradually. But the same load, applied instantaneously can and
has caused complete failure.
