Hi, Could someone please tell me if there is a way to use "stress versus axial shortening" curves from experimental data to define the work hardening part of the stress - plastic strain curve in MARC. The manual says the data has to be from tensional experiments to define them in a tabular...

Hi I have been trying to model power law creep is abaqus using the standard time-law hardening option. The following are the values I am using: Youngs Modulus = 55e12, Poisson's ratio = 0.25 A = 2.9e-37, n = 3.3, m = 0. (My model length unit is in Kms (not meters); hence the unusual numbers...

Hi, I am trying to create a solid in the assembly section, but I am running into these errors - "The depth reference should not be on the section plane" and "Could not determine feature depth. #QUICK FIX, #REDEFINE/#REROUTE" The same technique worked before, so I am clueless what is going...

Hi, Is there is a way to get the orientations of the principal strains/stresses directly from CAE ? thanks SS

Hi I have a Patran database that I created in a SUN system about 3 years ago. I tried opening this database in Patran (2006) on a windows machine and it is giving an error that it needs to converted at the source. Unfortunately I do not have access to the SUN system anymore. Can someone...

Hi I have MARC input files that I created 3 years ago using a SUN. I had to get back to them after 3 years now. For some reason, I am not able to retrieve the input file without errors. I have been trying to use these input files to create a new job in MARC MENTAT 2007 on a windows machine. I...

Thats exactly right. I deleted them by mistake.

Hi, Could someone please tell me if it is possible to retrieve a .DAT file (input file) from .T16 file (results file) ? Thanks in advance SS

Hi, I want to define an elastoplastic material in CAE. The yield strength is dependent on the confining pressure. I have the stress vs. strain curves for different values of the confining pressure. Could someone please suggest me if there is a way to define different plastic...

Hi, I have been trying to run an analysis with remeshing option from CAE. The following is the error I am getting Error in job TwoFauilts061909_remeshing: Unable to delete file(s) ["C:\\Temp\\TwoFauilts061909_remeshing.023", "C:\\Temp\\TwoFauilts061909_remeshing.dat"...

Hi Rob, Please find attached the geometry in my model in a stp file format. Please let me know how if you think I can use it to partition the inner edges (ie., edges that lie completely inside the upper model block). I will also look up into paritioning the face (using edge offset or...

Thanks Rob and rmettier ! I will try both your suggestions and see what happens. I will update the status on this thread. Rmettier, The elasto-plastic hardening values for Granite and Sandstone are from published articles. These are for testing my models only; Here are the...

Hi, I have been trying to develop a 2 layered large scale model for geological applications. Due to the nature of the problem, I have to define contacts (10) between all surfaces that can come in contact with one another during the analysis. When I run the model, it runs just fine for...

Hi Xerf, Could you please clarify what you mean by importing into explicit analysis ? Is it the same as 'restarting' the model in explicit after importing the job results from the geostatic state ?

Hi Gurmeet, Unfortunately, I am not able to unpick the edges in the same manner (using the cntrl key) to exclude the edge nodes from the contact definition. As soon as I edit the contact (using cntrl key), somehow all the edge nodes still reappear when the contact is...

Hi, I am trying to set-up a large scale geological model (80 Kms x 80 Kms x 12 Kms) in Abaqus explicit. Is there a way to set-up, through cae, a geostatic step followed by an explicit analysis for the same model ? I am using the geostatic step to make sure that gravity is at its full...

Thank you all for the suggestions. The surface that I mentioned is a complex 3d surface that I generated in ProE. It does not have a regular geometry (e.g., square etc.,). So I am not very sure how to partition it. The reason why I am trying to unpick an edge is to avoid over constraints on...

Hi, I am trying to define contacts in Abaqus, but I am running into a problem. I want to define a slave surface which is composed of a surface 'minus' the nodes along a selected edge of that surface. Is there a way to do this in CAE ? I tried unpicking the edges using 'ctrl' button in CAE...

Hi, Is there a way to contour the sliding distance (of slave surface w.r.t master surface) on a deformable contact in CAE ? I tried using Tangential motion at nodes option, but Abaqus is saying "Variable not available in display group". All I want it to see how much slip is there on the...

Hi, This is the last set of questions for now :-) I have a completely working model that I developed in Standard. Now I want to set-up the same model in Explicit. The reason being that I have shear fractures modeled as simple sliding contacts (in Abaqus Standard). I want to use Explicit to...
