Plastic Models for Dynamic Structural Analysis

Scaled plastic models can be used to predict the dynamic response of complex structures, particularly critical frequencies and mode shapes. The basic advantage in model design analysis is the flexibility in altering initial concepts at early stages of design, which can be accomplished quickly, simply, and at lower costs than would probably be encountered if the structure were fabricated in the prototype material. This paper presents the use of plastic models as a design tool for stamped, welded steel automotive structures and subsequent engineering tests.
