Resistance Fail Strain Gage Technology as Applied to Composite Materials.

Abstract

A general review of existing strain gage technologies as applied to orthotropic composite materials is given. The specific topics addressed are gage bonding procedures, transverse sensitivity effects, errors due to gage misalignment, and temperature compensation methods. The discussion is supplemented by numerical examples where appropriate. It is shown that the orthotropic behaviour of composites can result in experimental error which would not be expected based on practical experience with isotropic materials. In certain cases, the transverse sensitivity of strain gages and/or slight gage misalignment can result in strain measurement errors exceeding 50%.
