- Abstract
The balance principle of the strain gauge arrays observation is analyzed in detail according to the first invariant of the stress. A partly damaged strain gauge arrays' strain conversion is discussed. The stress computation through the strain gauge arrays under different condition is confirmed. A method for determining the validity of the strain gauge arrays is studied and summarized. A collection procedure containing the strain gauge arrays' validity judgment, strain conversion, and stress computation is established based on the causal relation model.
