Title:
The investigation of state of inhomogeneous elastic plastic tube by small parameter method
Keywords:
elastic-plastic, thick-walled tube, convergence, method of small parameter.
Abstracts:
We considered the elastic-plastic tube made of non-uniform material under the action of internal and external hydrostatic. The contours of the cross section are close to circular. The inhomogeneous material and the deviation of the section shape from the canonical characterizes by of the functions known to small parameters. We found a condition defining the boundary of the convergence region of the perturbation method. We obtained a solution describing the stress-strain state of the tube up to the first order of terms.
