Translational Stiffness Time Step

$Δ t_{t r a n s l a t i o n a l_s t i f n e s s} = \frac{\sqrt{m a s s . \max (K t) + C_{t}^{2}} - C_{t}}{\max (K_{t})}$

Where,

$Δ t_{r o t a t i o n a l_s t i f n e s s} = \frac{\sqrt{i n e r t i a . K_{r}^{'} + C'_{r}^{2}} - C'_{r}^{}}{K_{r}^{'}}$

$K_{r}^{'}$ is the equivalent rotational stiffness: $K_{r}^{'} = \max (K_{t}) . L^{2} + \max (K_{r})$

Where,

$\max (K_{t})$: Maximum translational stiffness
$\max (K_{r})$: Maximum rotational stiffness
$C'_{r}^{}$: Equivalent rotational damping: $C_{r}^{'} = \max (C_{t}) . L^{2} + \max (C_{r})$

Where,
