/IMPL/DYNA/2

Engine Keyword Describes the implicit dynamics with a general Newmark method.

Format

/IMPL/DYNA/2

$γ$ $β$

Data	Description	SI Unit Example
$γ$	Implicit dynamic with general Newmark method. (-2 $β$ ≤ $γ$ ≤ 1/2) $γ$ , $β$ =0 set to $γ$ =1/2; $β$ =1/4.
$β$	Implicit dynamic with general Newmark method. (-2 $β$ ≤ $γ$ ≤ 1/2) $γ$ , $β$ =0 set to $γ$ =1/2; $β$ =1/4.

The nonlinear parameters, rather than default values can be defined in /IMPL/NONLIN.
An α-HHT method is the default implicit dynamic method, if /2 is omitted.
