how to connect different parts
how to connect different parts
(OP)
Hello,
I am trying to simulate a pushover test of a brick wall supported by a metalling plate at the base that will keep in his place without any connection at the edges in order to prevent the generation of traction forces.
I am not able to define the right coupling between the bricks and the steel support, I tried to use a kinematic coupling but I it didn't prevent the parts penetration.
Which connector or constraint should I apply at the interface in order to solve the penetration problem without blocking the X direction?
Thank you in advance,

Just something general about couplings, and their use for applying a remote force.
For SHS or a CHS, the point of load application is many times on the centreline of the section, thus there is no node there. In Strand7, which is the software I use, one can use a rigid link cluster/spider, or a multi-point link cluster, to obtain a node (remote point) on the centre line where we can apply the load onto. Very often these two are what is called RBE constraints (Nastran name), and are more specifically RBE2 and RBE3 respectively in Nastran (often used like explained here for remote load application). These two translate as kinematic (RBE2/rigid link) and distributed (RBE3/multi-point) coupling in Abaqus.

I used contact interaction, more specifically surface to surface contact and I applied a small friction coefficient since I tried to impose the frictionless but it gave me an error.
So can you tell me please what are the default properties that you already suggested to use?
