Kirje Layer growing/removing method for determination of residual stresses in orthotropic non-homogeneous cylinders(International Centre for Diffraction Data, 2009) Kõo, Jakub; Valgur, JaakA unique algorithm of layer growing/removing methods for computing of the residual stresses in the incompletely orthotropic layered circular cylinder is presented. The stresses are calculated from strain measurements on the free stationary surface or from strain measurements on the cylinder's moving surface. The suggested algorithm is programmed for PC. As an illustrative example, residual growth stresses in a stem of Japanese red pine are computed from initial stresses measured on its free outer surface.Kirje Layer Growing/Removing Method for Determination of Residual Stresses in Thin Orthotropic Inhomogeneous Discs(Trans Tech Publications Ltd, 2026) Kõo, Jakub; Valgur, JaakAn algorithm of the layer growing/removing method for computing of the residual stresses in thin orthotropic inhomogeneous circular disc is presented. The stresses are calculated from strain measurements on the free stationary contour or on the lateral surface, or from X-ray diffraction measurements on the disc’s moving contour. The suggested algorithm is programmed for PC. Two illustrative examples are presented.Kirje Residual stress measurement in goated plates using layer growing/removing methods: 100th anniversary of the publication of Stoney's paper "The tension of metallic films deposited by electrolysis"(Trans Tech Publications Ltd, Switzerland, 2011) Kõo, Jakub; Valgur, JaakIn connection with the 100th anniversary of Stoney's equations, some historical remarks are made with respect to the development of these equations. As an example of the extension of Stoney's equations, a unique algorithm of the layer growing/removing methods is presented for determination of residual stresses in isotropic inhomogeneous coated plates. Using a computer program based on this algorithm, residual stresses are computed in the galvanic steel coating on the copper plate substrate.
