Dynamic instabilities of frictional sliding at a bimaterial interface

Submitted by Eran Bouchbinder on

Understanding the dynamic stability of bodies in frictional contact steadily sliding one over the other is of basic interest in various disciplines such as physics, solid mechanics, materials science and geophysics. Here we report on a two-dimensional linear stability analysis of a deformable solid of a finite height H, steadily sliding on top of a rigid solid within a generic rate-and-state friction type constitutive framework, fully accounting for elastodynamic effects.

Have someone met a strange behavior of Load-Displacement curve in a simple 2D indentation problem

Submitted by minhtran.1986.vn on

I am modelling a very simple 2D contact problem between a rigid wedge indenter and a deformable squared-shape specimen (general steel material) in frictionless contact case. I used an implicit function f to describe the rigid indenter.



I implemented Lagrange multiplier method for this contact problem and the contact condition is: Inside the contact zone of the deformable specimen, the node set is active if f(node)<=0 and the Lagrange multiplier lambda<=0.



Can someone explain the strange physical behavior in contact problem using Lagrange method in modeling a simple 2D indentation?

Submitted by minhtran.1986.vn on

I am modelling a very simple 2D contact problem between a rigid indenter and a deformable squared-shape specimen. I used a implicit function f to describe the rigid indenter. 

The contact condition is: Inside the contact zone of the deformable specimen, a node n is outside of rigid indenter for f(n)>0, and inside for f(n)<0. In case f(n)=0, the contacting node lies on the surface of the rigid body.

Large deformation spherical (hertz) contact simulation

Hello Everyone,

I am simulating contact of a sphere with a soft elastomer (Hertz contact). Unlike the hertz contact, I will like to simulate large deformations. My model is a 2D axisymmetric model and the load is displacement controlled. The current model fails at total time/freq ~ 0.84. I have tried refining my mesh and have reduced the increment size and increased the number of increments. Currently, step my parameters are:

 Max. number of increments: 200000 and Increment size:0.005/1E-5/0.01

 Nlgeom is On because of the large deformation.
