Abstract

The distributive elastic properties in nonlinear structures is characterized using an inverse elastostatic approach of stress analysis using assumed elastic models without knowing the realistic material parameters. Stress distributions are computed independently of strain measurements. A database of pointwise stress and strain data in regions of the nonlinear structure permits the elastic properties of the structure to be characterized point-by-point to provide the property distribution.
