VUHARD

hello

I works with subroutins in ABAQUS.

I have written a vuhard subroutin and I have some problems.

who does work with this subroutin that can help me?

With regards

deformation of a clamped circular plate

circular plate

clamped

Hi all,

I need help to calculate the deformation of a circular plate(d=200mm and t=10mm) with a hole (d=20mm and t=5mm) at a center. The plate is clamped at its edge and subjected to 275KPa uniformly distributed load at the face without the hole.

I want to study the variation of maximum deformation with the varying depth of the central hole. Any ideas on how I should approach this problem?

Why shape function is kept orthogonal to residue in Galerkin method?

I have a question regarding the shape functions. Why the shape function is kept orthogonal to residue in Galerkin method? Looking forward to hearing from you all.

Creep strain vs time graph as input in abaqus

creep

I have a creep strain vs
time graph. How can that be used as input for creep? In defining creep,
abaqus asks for power law multiplier, eq stress order and time order?
how can those be found from creep strain vs time graph?

What are the regular iteration steps of cohesive model based FEM for crack problems

Submitted by Wen Ye on Sun, 05/04/2014 - 12:25

Hi,

I'm now start to learn cohesive zone model based FEM for crack problems. According the a regular coehsize model (bilinear for example), the relative displacement and the cohesive stress are both unknwon, so iteration is required. My question is that what are the regular iteration steps?

Thanks.

Dear all

I want to model 300000 cycles of loading with maximum and minimum value for force as a fatigue loading.I want to model this problem in abaqus and I have several idea for it but not sure about them.would you help me what to do?

many thanks

Topology optimization

Structural topology optimization, which aims at placing available material within a prescribed design domain appropriately in order to achieve optimized structural performances, has received considerable research attention since the pioneering work of Bendsoe and Kikuchi. Many approaches have been proposed for structural topology optimization and it now has been extended to a wide range of physical disciplines such as acoustics, electromagnetics and optics.
