Experimental and Finite-Element Study on Cyclic Tensile Properties of Stainless-Clad Bimetallic Steel Plate
The stainless-clad bimetallic steel plate (SCBSP) formed by cladding a layer of stainless steel on the surface of a mild steel plate is a solution to improve the corrosion resistance of steel in corrosive environments To study the hysteretic behavior of stainless-clad bimetallic steel plates under cyclic load, tests of 14 specimens taken from Q235+S34553 SCBSP with normal thickness of were carried out, in which 14 different loading protocols were incorporated. Based on the test results, the hysteretic behavior of the SCBSP specimens was analyzed. The envelope curves of the SCBSP under cyclic loading were fitted based on the Ramberg-Osgood model (R-O model), and the energy-dissipation capacity of the SCBSP was evaluated by calculating their energy-dissipation index (EDI). Finally, the Chaboche combined hardening model was employed, its relevant parameters were identified, and the identification results were verified by finite-element simulation. The results show that SCBSP has good energy-dissipation capacity. The R-O model and Chaboche model can well express the mechanical behavior of SCBSPs under cyclic loading.
