RE: Static vs dynamic

Static:  steady-state (or long-term) response with no inertial or time-dependent effects (solved using [K]{u}={F}, unless a material nonlinearity (e...g, hyperelasticity or plasticity) is present, in which case the tangent stiffness and incremental displacement and load vectors are used – [Kt]{du}={dF}).

Quasi-static:  Time-dependent response with no inertial effects.  Time-dependency is in the form of creep or viscoelastic response (solved using [Kt]{du} = {dF}).

Dynamic:  Time-dependent response with inertial effects.  Solved using [M]{a} + [C]{v} + [K]{u} = {F}, if implicit time integration is used, or {a} = [M]^-1 {F}, if explicit time integration is used.  In your case, you’re almost certainly using Abaqus/Explicit.

Please refer to the Abaqus Theory Manual, or virtually any good finite element textbook for further information.

Subject: [EXTERNAL] [Abaqus] Static vs dynamic


Hi all,

I am writting a thesis on Explosive metal forming and therefore I am doing simulations on Abaqus,
I was wondering if you could help me understand the differences between static, quasi static and dynamic analysis on abaqus.

Thanks a lot,

Emmanuel
