Abstract:
In this paper, the ratcheting behavior of stainless steel 304L cylindrical panels under cyclic combined and axial loading is studied. Experimental tests were performed by a servo hydraulic INSTRON 8802 machine for several samples. The panels were fixed in normal and oblique directions under 20 degrees and subjected to cyclic loads. The effect of the length and angle of the cylindrical panels on ratcheting behavior and plastic energy was investigated. Based on the experimental results, it was found that bending moment played a crucial role in the dissipation and increase of plastic deformations. The ratcheting displacement for a cylindrical panel under combined loading is larger than for one under uniaxial loading, because the bending moment cooperates with the axial load to increase ratcheting displacement for cylindrical panels under combined loading. Also, for several cycles at the beginning of loading, the ratcheting displacement rate of the panel under combined loading was higher than that of the one under uniaxial loading. Finally, the ratcheting displacement rate of both types of loading became equal. The results showed that when the length of samples increased, ratcheting displacement and plastic energy increased, and sample life decreased.
