Does anyone have any good references for the discussion between the relationships between fatigue and fracture components? Thanks.

Hello all I am new to Autodesk inventor 12 This is a very simple question, but would be useful to know how to select hidden surfaces which are covered by other surfaces. It's easy when you now how :-) thanks.

Hello all, After conducting lots of Abaqus Standard/static analysis. I am now looking at using Abaqus Explcit to model impact. I am starting off with a simple impact analysis, however I am finding i difficult to reach a solution. What should I be looking for as an indicator to during the...

Does anyone know of any good software to model kinematics (other than MSC Adams). I am interesting in modelling a motion problem and then extracting the position data during the movement. Thanks I look forward to hearing from you all.

My particular problem involves contacts and I have decided to conduct a dynamic implicit analysis (i.e. considering the density of the material) and standard static analysis. Am I correct to assume that if, the stress results are the same for both analysis then I can ignore the dynamic/intertial...

Hello all, Is there anyway I can model two components in Solidworks, position them and determine the contact area between them? I that the contact area will depend on the load between the components, just wondered if anyone had any thoughts/experience with this? Thanks.

Hello all, I am running out of space options for analysis on my machine. Does anyone use an external hard drive to run Abaqus analysis directly from. Alternatively, does anyone encounter any problems transfering analysis from the C:/ drive to the external HD and getting corrupt files when you...

Hello all, I am looking into using XFEM to assess fracture risk and crack initiation between two components in contact. Does anyone have anyone experience using this technique at the micro scale and subsurface levels? I am not even sure if that is possible? Is there any good reference I can be...

Hi all, I am using Mechancial Engineering Design by Shigley/Mischke Sixth Edition. I noticed on page 367, there is an equation with the parameter "Su" ('S' subscript 'u'), however, I can not find the definition of "Su". Is this supposed to be the same as "Su" ('S' subscript 'ut' which is...

Through conducting a a dynamic implicit analysis using FE I am trying to make an assessment if inertial effects in my model can be ignored. If I were to compare the kinetic energy and strain energy under impact and check that there they are both negligible would this be a good enough indication...

Hello all, This is a very quick terminology question. Is elastic potential energy the same as strain energy? Thanks.

Hello all, Running some projects on FE, one of them is a Abaqus/Standard model. with contact by displacing (to reduce gaps bwteen components) and then loading components together. The kinetic energy of the total model "ALLKE" seems to be zero throughout all the steps. Is there something wrong...

Hello all, I am trying to find the techniques to finely mesh a part i.e. with e.g. 10 elements connected to 1 element. Please see the attached image to hopefully explain further what I am trying to achieve in 3D. As I can't see to achieve this with partitioning the 3D model. Will I need to...

Hello all, I need to look into possible work stations for Abaqus. Can anyone suggest any good systems? I would be interested in price comparisons of 32BG, 64GB and 96GB machines with a decent process to match. I look forward to any suggestions and advice.

Hello all, I have a solid section femur and need the first 1.5mm thickness from the surface to be one material property and the rest of the solid section be another material proerty. This would represent the first 1.5mm thickness of the bone being cortical bone and the internal structure being...

Hello all, I am doing a convergence study on a two body contact problem. I have been using global seeds to increase the number of elements for each run. However when the run times were getting too long I switch to edge seeds and really refined the mesh in the contact area and more coarse mesh...

Hello all, I am a little confused with abqaus, I have parts in contact which show stresses and contact pressure, however all my Reaction force plots RF are zero and I don't understand why? Can anyone help? Many Thanks.

Does anyone know how I can calulate the shear srength of a material from the standard mechanical properties of materials, such as Tensile strength, youngs modulus, bulk modulus, elongation, rockwell hardness, and yeild strength? Thanks.

Hi all, I have solid 3D deformable models in contact with analytical rigid surfaces. When I try to visualise the model (i.e. Von Mises Stress) through a view cut it turn hollow in the middle. I get the following message.. "Vuew cuts through swept analytical rigid surfaces are not supported...
