New release now available for the Mimics Innovation Suite

Submitted by Mimics on

Leuven,Belgium, May 31, 2011. Materialise is proud to announce the newest release of the Mimics Innovation Suite. The software solution, already renowned for being the fastest  and easiest method for getting accurate 3D surface models from imaging data, is now faster and more user-friendly than ever. An example of the improved features is that several

How to simulate compaction process of powder mettalurgy in Abaqus?

I am doing ph.d work related to powder mettalurgy 

I want to simulate the compaction process ( in powder mettalurgy) by using ABAQUS.It is very essential to find a way to create a model which will behave as such as PM part.

After modeling it is next work to find the proper analysis method to do analysis by applying compressive load to study the deformation of the PM Part. In ABAQUS, Modified Drucker-Prager cap model is widely used for the compaction problems of different metals in many research papers.

I have 2 problems.

Simple Cell Traction Force Script for Elastic Micropatterned Substrata

Submitted by srp215 on

Hi readers, 

 This is MATLAB code that was written by myself and collaborators that we've sought to make available to the wider research community. The program is intended to track the displacements of micropatterned dots on a substrate in a similar manner to that performed by  Maloney et al. in "Influence of Finite Thickness on cellular adhesion-induced deformation of an compliant substrata".

sweep mesh of a dome in ANSYS

Submitted by tunl on

I am dealing with a partial sphere dome in ANSYS, I created the volume by extruding half of an arch area along the axis at the dome center. I am using SOLID65 elements. The problem I am facing now is how to properly sweep mesh the whole volume ( actually, there are four 90 degree partial sphere together after the extrude of the area), because if I simply sweep the volume, the elements around the top center of the sphere will cause element shape warning in the static analysis.

Dose anyone have any idea about how to deal with the mesh around the center?

Output of ABAQUS for contact of a rigid surface with a poroelastic layer

Submitted by RM on

Hello, I am modeling the spherical indentation of a poroelastic layer. I am modeling the indenter as a rigid analytical surface. As you know, the total pressure in a porous medium at each point is the sum of the elastic stresses from the matrix, and the pore pressure caused by fluid pressurization. Abaqus provides both the pore pressure and of course the rest of the stress quantities.



Abaqus Script Manual/Tutorial

Submitted by Johannes T.B. … on

I have written a introduction manual/tutorial on Abaqus Scripting. I got some good feedback from my colleagues. Therefore, I would like to share the manual.The manual should give a short introduction (it will not take more than one hour) to Abaqus script in Python.

You can find the manual here:

Abaqus Script Manual

Via the same link you can also find more information on the connection between Matlab and Abaqus

Good luck!

Defining density as a solution dependent variable in VUMAT (Abaqus/Explicit)?

Submitted by Shunlai.Zang on

Hi All,

I am trying to simulate tooth deformation. It involves that the density of tooth changes with deformation. I want to know is it possible to define density as a solution dependent variable in VUMAT?

 Thank you in advance!

Simulation of wave propagation in ABAQUS/CAE

Hi, I am working on modeling wave propagation in ABAQUS/CAE.

I am not expert on ABAQUS and trying to figure out how it works.

I have a 2D Shell steel plate (1 centimeter by 1 centimeter) and try to obtain wave speed at any points of plate.

I put the material properties in and used ABAQUS/Explicit analysis.

Time steps are 1E-009 seconds and there are 2 steps (impulsed at the first step and propagates at the second step).

The load pluged at the amplitude with equaily spaced for 0.1 micro seconds (so it becomes impulse load).
