Hi I am working on the designing of a crash test bench to measure vehicle door intrusions ?
Could some one provide me basic ideas on the test bench set up and how to mout the door on the test rig and which degrees of freedom to lock ?.
We know that for non-linear finite element analysis, we generally have 2 formulations:
1)Total Lagrangian formulation
2)Updated Lagrangian formulation
In the Total Lagrangian the refernce frame at t=0 is used i.e. all the integrations are carried out using the original volume and surface area and the sterss measures generally used include the Second Piolla and Green Lagrangian strain
I am working on the orthogonal machining of Ti alloys using ABAQUS F.E package. I am carrying out an explicit dynamic temp-disp problem. My doubt being on what parameters does the Total energy of the analysis depend upon. Any help would be appreciated.
Thanks in advance!
Hello!
i have a problem with abaqus with the message error "too many attempts made for this increment" : mu model consists od analyzing the effect of plastic anisotropy in deep drawing process .I can't find the cause of the problem ,or any thing on wich i can actin order to make things work.Could anyone help me please !!
Thanks in advance!
hi,
i'm looking for a pdf version of the book " computational contact mechanics"
PLease do some one could help me with !!!
i'm seraching exactly about lagrangian multiplier method and penalty method for contact problems and this book may contain what i'm searching about.
Hello,
I have some troubles in calculating the strain in ABAQUS. I have the following Model with one element (see picture) and a linear elastic isotropic Material (Steel), which is sheared in the x-direction. The analytical result of the strain tensor gives me in xz-direction 0.25 (see picture). The result in ABAQUS is 0.5. I ran the same simulation in CalculiX CrunchiX and got the expected strain of 0.25 in the xz-direction
Can anyone tell me how ABAQUS calculates the strain for a linear static analysis? Why is the ABAQUS result exactly 50% higher?
Hi All
usually there is few information about damage models for low carbon steels, I have been searching in literature, but there is nothing , shall anyone inform me , I am searching for C4 steel damage data
Thank you
Helo everyone,
I modeled a composite vibration analysis in Abaqus. Can anybody tell me how to find the stiffness matrix from the odb file?
Thanks
I m trying to apply to apply plastic strains initial conditions in Abaqus as you can see below :
** ----------------------------------------------------------------
*Initial Conditions, type=PLASTIC STRAIN
test_elements, 0.338, -0.276, -0.0618, 0.0447
**
** STEP: Step-1
This part of code works in case of Stresses but not for plastic strains... The calculation presents no errors, abaqus runs but when i check the results, it doesnt consider my plastic strain...
An example of INP file :
