im using 2D Shell elements

Hi frds, Im new to patran/nastran. Nonlinear implicit SOL 600 Have anybody done cotact analysis for composite materials(Deformable) with a rigid body in Patran /Nastran? i cant make a successful one? im getting errors sayig: During the approach stage of a CONTACT analysis, a rigid body did...

Hi frds, Im new to patran/nastran. Have anybody done cotact analysis for composite materials in Patran /Nastran? i cant make a successful one? can anyone help me?

hi frds thx for all ur replies sorry for the late response i found the solution the problem was that the number of temperature points in thermal file does not match the mechanical files i need to specify it as piece wise linear to the number of integration points. it will be done in the...

Thx for ur suggestion xerf will yos suggest me a suitable step for doing my analysis? thx

Hi frds, I am using ABAQUS CAE 6.6-1 I am simulating a Shell subjected to a temperature change(for eg., 350 to 500deg C) and with some mech BCs. I am able to do this in a static step ,by giving initial temperature field in initial step(for eg., 350deg in predefined field1 in initial step)and...

Hi friends Could anybody tell me how ABAQUS will computes the stress values and averaging.is there any explanation available in the Documentation? if so plz give me the link.i couldnt able to find anything thanks in advance sheriff

Thanks Martin i will look for some other packages but im in a situation to do in ABAQUS i will wait for some more replies

HI, I want to model solidification of a metal which is in a molten state over another metal Could anybody tell me How to define a model in Abaqus as a molten (liquid) metal? what type of element shud i use ? is thr any examples for modelling solidification and other requirements thx in...

hi i have created a solid shell composite element with two different materials (for ex steel and glass)and i gave the thickness and integ points how abaqus will define a composite materials? i mean in which order? top surface is steel and bottom as glass like that? i can find the various...

hi i got the answer from my frd i have to specify the section points in the field output requests thx

hi I have created a composite shell with two different materials and i want to get the output at every integration points in the layers by using CAE not by input file i have found this thread thread799-63482 with the similar problem cud anybody help me to get the output in all the integration...

i dont come across this error before just i am applying a uniform temperature of 350° C to the composite material steel and glass by importing the material properties of comp material and copy the material model to my model AttributeError: 'None' object has no attribute 'getData' Error in job...

thx corus i rectified the problem it was some mismatch of path location as u said for example i browse and select from my path C:/Documents and settings the unix system doesnt accept the space between documents ¨-¨and¨-¨settings that was the problem and we shud have the part file .prt with...

hi frds I am working in ABAQUS CAE and i want to use an odb file as an initial condition and i have specified the file in Step--> initial--> Field and created a field and included the file by selecting in Field editor dialog box-->distribution--> From results or output dbfile--> and select...

Hi josep u mean the results or the value of forces at each node ?

thx martin i ll try to find

the error message is exactly like this¨Too many attempts made for this increment¨

hi Error: Too many attempts for Increment wat does this error really means?
