Web– A bisection in time is a bisection in ramped loads – If load is Zstep applied, bisection has no benefit – Ramped vs. Stepped controlled by KBC ... • Rare in recent versions of ANSYS • Subtle changes in mesh can perturb solution off instability point • Alter FKN by 5-10X lower. – Verify acceptable penetration WebIn humans bisecting short durations (<1 s), Wearden and Ferrara (1996) found bisection at the geometric mean with an L:S ratio of 2:1, but with larger ratios, the bisection point was closer to the arithmetic mean. With longer durations in the seconds range, bisection was not at the geometric mean with any L:S ratio, including 2:1 ( Wearden et ...
