Hi all,

After several simple testing, i've just realised that why the max principle strain and E11 strain came out different when applying tension at one end and clamped the other end. Initial i stretched the panel to be extended by 0.28mm so that it was expected to have 2000 microstrain on the composite panel having 140mm in length. When viewing it with max priciple strain i've got 2000 microstrain but with E11, 714 microstrain only.

With LS-Dyna, they gave the same values.

Much appreciated if anyone can explain this to me.

Regards,
minki
