Abstract
This paper describes an investigation of plastic instability of an internally impulsively loaded thin-walled spherical pressure vessel with plastic orthotropy. In the framework of finite deformation and Hill’s orthogonal anisotropic yield criterion, the vessel instability strain is derived, which includes the effects of the plastic orthotropy and strain rate.
