The decay ength is a characteristic length corresponding to the
component geometry,i.e.,shape of the shell and its dimensions.Larger decay length generally indicates better energy dissipation of the structure and leads to higher loading capacity whereas smaller decay length suggests severe local effects due to the applied forces.Once the decay length associated with the component geometry is obtained,the reference volume can be calculated from the size of the damaged zone.The decay length is also used to identify the possible interaction of multiple local damages.If there are two separate damage zones whose decay lengths (reference volumes) do not intersect,the two damage zones are completely independent.Otherwise,the interaction effects must be considered.It must be pointed out that the reference volume simply identifies the region that participates in plastic action.The failure will still be due to primary stresses even if the reference volume is identified using bending or other similar effects.
