Nastran laminate export options for PCOMP and PCOMPG cards

Laminate Option	Stacking Recipe	NASTRAN Definition	LAM field of PCOMP card	LAM field of PCOMPG card
None	≠ Symmetric	All the plies are specified on the PCOMP or PCOMPG cards.	Blank	Blank
None	= Symmetric	Only plies on one side of the mid plane are specified on the PCOMP card.	SYM	N.A.
MEM	all	All the plies are specified, only membrane terms are retained.	MEM	MEM
BEND	all	All the plies are specified, only bending terms are retained.	BEND	BEND
SMEAR	all	All the plies are specified, stacking sequence is ignored, shear and bending-membrane coupling terms are set to 0.	SMEAR	SMEAR
SMCORE	= Symmetric with Core	All the plies are specified, the last ply is the core, stacking sequence is ignored, shear and bending-membrane coupling terms are set to 0.	SMCORE	SMCORE
SMCORE + transverse shear	= Symmetric with Core	Similar to the standard Nastran SMCORE option, except that it also provides transverse shear stiffness.	N.A.	N.A.
