Design by analysis of ductile failure and buckling in torispherical pressure vessel heads [PDF]
, 2008 Thin shell torispherical pressure vessel heads are known to exhibit complex elastic-plastic deformation and buckling behaviour under static pressure. In pressure vessel Design by Analysis, the designer is required to assess both of these behaviour modes ...
