In uniaxial tensile checks on ductile rate-independent sheet material, plastic instability and circulate localization occurs just after the utmost load when diffuse necking begins. But, after the onset of a diffuse neck, deformation continues under a falling load till the development of a localized neck then ductile fracture . Secondary strain localization is determined by} the shape factor (width/thickness) of the tensile test-piece and the Socket Organizer fabric strain hardening . Large width/thickness ratios and small strain hardening parameters result in localization in the width of the specimen. Whereas, small width/thickness ratios and large-strain hardening parameters trigger through-thickness localization.
