Experimentally Determined Full-Field Stress, Strain and Displacement Analyses of Perforated Finite Members

The integrity assessment of an engineering structure or member often requires knowledge of the full-field individual components of stress, strain and/or displacement. Evaluating these can be difficult for finite structures, contact problems, or if the material properties, loading or boundary conditions are unknown. Theoretical stress analyses of finite perforated geometries are virtually impossible. Both analytical and numerical techniques necessitate knowing the boundary conditions, the latter often being unavailable in practice. Results show errors can occur as one approaches a purely boundary collocation approach. Combining experimental information with analytical and numerical tools enables one to solve aforementioned situations. For example, values of a single component of displacement are used here to determine full-field individual components of stress, strain and displacements in isotropic or orthotropic structures and without explicitly differentiating the measured displacemen
