# sc-strn = small cycle Strain ampl
# ol-strn = overload strain ampl.
# eta = no. of small cycles between ol cycles
# block = 1 overload cycle + eta small cycles
# Bf = no. of blocks to failure
# n_ol = nblocks * 1
# N_ol = Constant ampl life with only overload size cycles
# n_sm = nblocks * eta
# N_sm = Computed equivalent life of small cycles
# Equation: (Solve for N_sm )
# n_ol n_sm
# ------ + ------ = 1
# N_ol N_sm
