#L1= 60 # Distance from Top sheet grip/specimen contact point to centerline of weld

#Spacer2= 2.5 #Thickness of spacer no. 2
#Note: For loading line at faying surface: Spacer1 = G1 and Spacer2 = G2
#
#WeldWidth= 9 #length of weld fusion zone across the width of specimen.
# If WeldWidth .LT. Width then there a Start/Stop features are expected to
# exist in the weld line. If this is the case, then the weld is assumed to
# be centered in the specimen width.
# If WeldWidth=Width, then a continuous weld with no start and stop is assumed.
# More description can be placed into general comments.
#
#WeldOffset= 3 #Difference between specimen centerline [as measured from (L1+L2)/2] and weld centerline
#WeldSize= 5 #Root of weld size (weld throat size)
#WeldToeAngle= 30 #degrees
#
# Notes:
# 1) L1 has slightly different definitions based on the type of weld.
# It is always defined from the edge of the gripping system on the
# top sheet, but its terminus depends on the weld type:
# A) GMAW weld types the right terminus is at the weld heel (leftmost
# edge of weld as defined in drawing above).
# B) Laser and Butt weld types, right terminus is weld centerline
# 2) WeldLength is
# A) the horizontal leg length in GMAW weld types
# B) the actual fusion weld width in Laser and Butt weld types
# 3) L2 is always defined such that TotalLength=G1+L1+L2+G2
#
#TEMP= 21 # Temp (in Celcius) that fatigue tests were conducted at.
