• The effects of stiffness of the strain gauge adopted for measurements of principal residual stresses in a laminated anisotropic plate and of its base thickness on the measured values of strain components, have been clarified by numerical calculation after deducing the equations of the residual stresses as a solution of Volterra's simultaneous integral equations of the first kind. That is, since two different effects offset each other, the total effect decreases in case of a symmetrically laminated plate, whereas in case of a similarly laminated plate in which the relation of similarity holds among elastic constants in each element it can be reduced if the surface on which the gauge is bonded is chosen properly according to the gauge stiffness and base thickness.
