How to model fastener with same force-displacement behavior for all translational directions in a plane in Abaqus?

Choose a channel featured in the header of iMechanica: 

<p>Hi everyone. I want to model the fasteners connecting a wood sheathing to a steel frame in Abaqus. I want to input the same force-displacement behavior for all translational directions in the plane of the sheathing (like a radial spring). <br /> <br /> I was using spring element type Spring2 (nonlinear) but I could define behavior in only 2 translational directions in the sheathing plane (X and Z). This made my model overly stiff after the elastic range. I read about the RADIAL-THRUST connector element but it does not seem to be the one.

Sliding In Abaqus

Choose a channel featured in the header of iMechanica: 

Hello everybody.

 I am trying to use abaqus software to model the sliding of a metallic pile inside a metallic sleeve. I have tried doing this with the translator connector, but I always get the message that 2 regions in the model are not connected. Can anybody help me with some hints as to how to use the connector, or if there are any other ways to model the sliding? 

How to define reloading path of connector

Dear Abaqus user,

How to define reloading path in connector?

I am using cyclic load but the force-dip hysteresis behaviour is not correct as the connector reloading follows the previous unloading path which I want to define new reloading path.

ABAQUS model for special joint element and spring element

Very urgent two enquires:

1. How to model rotational spring element in order to define a curve
like M=k*(theta) where theta is the rotaional angle? It seems that
abaqus could only provide F=kx model.

 

2. there is a dashpot connector element which behaves like F=C * V
(where C is a constant), can I ask how to model F=C*(dv/dt)=C*a(where a
is the derivative of change of velocity)?

Thanks.
