Stability conditions of plastic deformation of thin-walled plates and shells under complex stress state

Using examples of uniaxial and biaxial tension of thin-walled metal or composite elements, the main hypotheses allowing to estimate the conditions of unstable deformation are explained. Specific estimations are given for a basic equation relating stress and strain tensor intensities as applied to pl...

Description
Summary:Using examples of uniaxial and biaxial tension of thin-walled metal or composite elements, the main hypotheses allowing to estimate the conditions of unstable deformation are explained. Specific estimations are given for a basic equation relating stress and strain tensor intensities as applied to plates, cylindrical and spherical shells. The equipment for testing tubular specimens under proportional loading under various plane stress states is described.
