Fcy of 6061-T4

Fcy of 6061-T4

Fcy of 6061-T4

(OP)
To do crippling analysis I need value of Fcy for 6061-T4 sheet per AMS-QQ-A-250/11. But MMPDS-01 doesn’t have the value of Fcy. Is there a way I can calculate Fcy value for 6061-T4?
MMPDS-01 states the value of 6061-T6 and –T62 per AMS-QQ-A-250/11.
Thanks.

Hi,

Since MMPDS does not deal with 6061-T4 I would think that MIL-HDBK5 values can still be used. HDBK5H gives Fcy=14ksi=96.5MPa for rolled and drawn shapes in the L-direction.

Hi MrHiLok

Andries is very close. The allowable values I have for  yield are 110 and 125 MPa for A and B basis respectively. Compression and tension yield are assumed to be the same.
