ABAQUS - NON-LINEAR FOUNDATION

Dear collages,

 

I'm trying to develop a non-linear analysis. I want to model a foundation as a shell, and I want to consider the stiffness of the soil (but I have to define also that the stiffness in traction is = 0, and in compression is equal to the Winkler module). I want to develop this model in ABAQUS software. Could anyone help to me?

Thank you very much.

Regards,

Juan José

Dears,  I am quite new in the area of Abaqus models and biomechanics. My background is related with textiles. However I am a post doc in Belgium at the moment and my new task is to model a fingertip skin section under the influence of contact with different objects.

Help for contact problem in tires

Submitted by pradeep632 on
research

HI

     I am trying to modeled a 3D tire assembly for a tire footprint. I assembled the tire, rim and the rigid-body as the road. I modeled the rim as an analytical rigid body. I am using STATIC GENERAL as the stpe with automatic stabilization. I have defined a following for the contact formulation in ABAQUS Standard:

1) Between the tire and road (analytical rigid-body):Surface to surface contact - Master surface: analytical rigid-body and Slave surface : the tire surface in contact with the rigid-body. The ineraction properties are:

Force to Expel Water from Between Two Plates

Submitted by Helen A. A. on

capillary

Hello,



I was wondering if anyone knew the equation to find the necessary clamping force to expel a saline solution out from between two parallel plates. I would like the most general form of the equation if possible, but will provide more details if necessary.



Thanks!

Effect of temperature on the stability of dielectric elastomers

Dielectric elastomer (DE) is a kind of electroactive polymer material,
capable of large deformation up to 380%. However, under conservative
operating conditions, DE is susceptible to instability with a small
deformation due to various modes of failure, including electrical
breakdown, electromechanical instability (EMI), loss of tension and
rupture by stretch. This paper proposes a free energy model in the
thermodynamic system of DE involving thermoelastic strain energy,
electric energy and purely thermal contribution energy to obtain the
stability conditions of all failure modes. The numerical results
indicate that the increase in temperature can markedly contribute to
improving the entropy production, the actuation stress and the critical
