Figure 9.
(A) Five periodic energy functions are shown, with arbitrary positioning on the y-axis. Each is shown with dimensionless energy barrier Πb set to 30, 25, and 20 for illustration, all under a dimensionless load of ΠP = 50. From top to bottom these are 3o, 4o, U, S, and V, as defined in the text. (B) Dimensionless time to failure is plotted from simulations performed with a system of 16 particles using each energy function over a range of values for Πb Each line style matches that of the function in (A) used to generate it.
