Abstract

Expansion methods are commonly used to compute the response at locations not measured during physical testing. The System Equivalent Reduction Expansion Process (SEREP) produces responses at finite-element degrees of freedom through the mode shapes of that model. Measurements used for expansion are often acceleration, strain, and displacement and operate only on like sets of data. For example, expanding acceleration data produces only additional acceleration data and does not provide insight into the test article’s stress or strain state. Stress and strain are often desired to evaluate yield limits and create fatigue models. The engineer may have acceleration measurements available but desire a component’s stress and strain state. This chapter evaluates a physical experiment from which acceleration is measured and a full set of strain, stress, and displacement data is obtained through SEREP and integration.
