Abstract: | Applied stresses on a residual stress model have previously been obtained by measuring the residual stresses and the resultant
stresses generated by applying a load. The present paper reports that the applied stresses and the residual stresses on the
residual stress model can be obtained by measuring two resultant stresses generated by applying loads of two different magnitudes.
In the proposed method, the residual stresses need not be obtained from the residual stress model before applying a load.
The residual stress model used to test the proposed method is a circular disk with frozen stresses that is subjected to a
diametral compressive load at a certain angle. The applied stresses and the residual stresses on a residual stress model were
experimentally and precisely obtained by digital photoelasticity using linearly polarized light. |
