Abstract

  The objective of this study is to develop a new stress analysis method for a steel plate with multilayered CFRPs under uni-axial loading. In the method, strains in each layer are considered to be state variables in first order simultaneous differential equations deriving from force equilibriums in infinitesimal regions. A general solution for strain is numerically calculated from eigenvalue analysis for a system matrix making from the differential equations. Unknown coefficients in the general solution are determined from continuous and boundary conditions for strains in each layer. In order to verify the validity of the proposed method, comparisons with analytical solutions, laboratory experiment and finite element analaysis were carried out. As a result, it was confirmed that the proposed method involved conventional analytical solutions, and made possible to analyze stress distributions of a steel plate with multilayered CFRPs.
