Previous linear bifurcation analyses have evidenced that an axially stretched soft cylindrical tube may develop infinite-wavelength (localized) instability when one or both of its lateral surfaces are under sufficient surface tension. Phase transition interpretations also highlighted the admits a final evolved ‘two-phase’ state. How localized initiates and evolves into state is still matter con...

The ductile fracture of thin-shell structures was studied here using a localized necking model. punching experiments for unstiffened and stiffened panels were compared with numerical predictions combined model shell elements. plasticity parameters JIS G3131 SPHC steel identified by performing calibration on standard flat bars, notched tension, central hole plane strain shear specimens. beyond t...
