Elastoplastical analysis on cylinder of different moduli in tension and compression

The constitutive equation was deduced. The results were obtained from the elastic and elastoplastical analysis of the cylinder sample applied with different ratios of load on both the inner and outer sides and different moduli ratio. The factors affecting the development of the plastic field of the...

Description
Summary:The constitutive equation was deduced. The results were obtained from the elastic and elastoplastical analysis of the cylinder sample applied with different ratios of load on both the inner and outer sides and different moduli ratio. The factors affecting the development of the plastic field of the cylinder with finite radius were shown. The results show that the different moduli ratio is the most important factor in the development of the plastic zone. The slight fluctuation of the ratio will bring multiplied increment of the displacement, which may result in the final destruction of the engineering material.
