GKN_history, 128 Turning points (Peaks & Valleys)

#This is a history provided to FD+E by GKN in the 1970s.  It was
#originally used to test Center Notched Plates. Kt=2.5,
#
# Material BS 4360-40B Steel
# Nominal Chem. appears to be  0.17C wt% 1.40Mn max, .045P max, .045 Smax
# Which is roughly a AISI or SAE 1522 (e.g.  here )

# Experimental Plate Test Results:
