Force/Pressure
(OP)
hi,
can we create a load on a surface other than a pressure. For example, on this surface there is a 10 kN force, and Abaqus find the equivalent uniform pressure for the selected surface ?
thanks

- only for linear elements (i.e. no mid-side nodes) could you attempt this, and then only on a regular mesh where all element faces are identical.

"Kinematic coupling is enforced in a strict master-slave approach. Degrees of freedom (DOFs) at the coupling nodes are eliminated, and the coupling nodes will be constrained to move with the rigid body motion of the reference node. "
"Distributing coupling is enforced in an average sense. Degrees of freedom at the coupling nodes are not eliminated. Rather, the constraint is enforced by distributing loads such that:
o The resultants of the forces at the coupling nodes are equivalent to the forces and moments at the reference node, o Force and moment equilibrium of the distributed loads about the reference point is maintained.
RE: Force/Pressure
and distributed coupling (sounds similar to a Nastran RBE3) at least it doesn't fix all the nodes together but will not apply a uniform pressure either !

Apply the loading in three cases, applying pressure, distributed or kinetic coupling loading.
