Abstract

The paper describes an hypothesis of shock damage that forms a useful criterion for the design of package cushioning. Using this criterion, the theory of shock isolation is developed and applied to both linear and nonlinear cushions. Although the present state of the art permits the design of the cushioning in a rational manner to meet specified requirements, it is difficult to determine the capability of the equipment to withstand shock and to define the severity of the shock to which the package will be subjected. Current procedures make extensive use of experimentally determined properties of cushioning material and apply the experimentally determined data directly to package design. Typical examples of such data are included, and references are given to more extensive compilations of applicable data.
