Abstract:

The objective of this study is to develop a new stress analysis method for a steel plate with multi- layered CFRPs under uniaxial loading. In the method, strains in each layer are considered to be state variables in the 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. For validation of the proposed method, comparisons with analytical solutions, laboratory experiment and FEA were carried out. As a result, it was confirmed that the proposed method included conventional analytical solutions, and made possible to analyse stress distributions of a steel plate with multi-layered CFRPs.
