Discrepancy of numerical results from analytical solution for an nonlinear viscoelasticity model

Submitted by aquis_mech on

  I have written a Fortran code for nonlinear viscoelasticity according to the Hughes' recurrence algorithm based on a total Lagrangian formulation.  And a relaxation test is made. There is some deviation from the analytical solution(Theoretically the stress response should be an exponential decay plus a constant, isn't it?). The numerical ultimate stress is larger than the analytical one. As a larger initial strain is applied, the deviation is smaller. For a inital strain of 10%, there is almost no difference between the num. and analy. solution. What can account for this?

Contact and XFEM?

Hi,



Initially, I asked this question to the Yahoo Group COMSOL
(FE package for multi physics simulation) because I thought, that there I
can find someone who is familiar with both COMSOL and Abaqus.
Unfortunately, among the experts of COMSOL I did not find an expert in
Abaqus.

COMSOL has an example 'Tube Connection' - a flange with four prestressed
bolts is subjected to tensile forces. To compute the influence of the
tensile force on the stress level in the bolt, the model includes a

Conference on Sustainable Construction and Design

Submitted by Reza Talemi on

On 16 and 17 February 2011 the Conference on Sustainable Construction and Design will take place. This event now comes to its third edition. Coming from a one-day event (called "Day of Research") where the research of our industrial and academic partners was presented, the conference has now grown to a scientific platform where the industrial and academic communities can exchange the latest research developments in following fields:
