Abstract: | Knowledge of individual stresses is necessary for the quantitative evaluation of engineering components. A finite element type scheme is described for accurately and efficiently separating measured isopachic data into individual in-plane stress components. Although the governing equations require complete boundary conditions to be well posed, illustrative examples demonstrate the method's ability to provide accurate individual stresses throughout a member using incomplete boundary conditions. |
