ØCan someone plese tell me whether an angle, i.e. a L shape has a plastic neutral axis. Because I have just used a program which gave me Zpl,x & Zpl,y ( second moment of areas ), as both equal to 0, for an angle ?

Intutively, for an equal leg angle, plastic neutral axes should be located close to the legs.

Plastic neutral axis are calculated by equating total area in tension to be equal to the total area under compression about the two principal axes, which in the case of equal angles are UU nad VV axes.
