Required Best method to simulate Over-Molded Parts

 

Hello

I want to simulate the Over-molded plastic part for static analysis. The part contains majority of plastic and some sheet metal inserts at different locations. 

I have the physical test data. and simulation methods that I have used varies largely from physical results.

Will you please tell me different methods from which I can have better correlation between physical test data and simulation results 

Thank you in advance

Queries on Nonlinear Large Deformation Analysis

 

Hello,

I have a few queries on Abaqus' implementation of Nonlinear Large Deformation Analysis :

1] While using user subroutines, e.g. DISP, the COORD variable represents the current configuration. Is there a way to access the coordinates of the original undeformed configuration in the user subroutines at any deformed configuration ?

2] Are there any abaqus variable that contains the following information in a nonlinear analysis: Green-Lagrange strain tensor, Second Piola Kirchoff stress tensor, Nominal Stress tensor ?


Thanks in advance for your advice and time.

Request for help

 

I am writing to ask your opinion about an issue in Abaqus/Implicit. I am doing Lamb wave analysis on an Aluminum plate. Dimension of plate is 600mm (L)*16mm (W)*5mm (H). Time period is 2e-4(s) and time step is 1e-7. When doing Abaqus/Explicit, I can easily enter tabular data of time and amplitude in amplitude toolset; however, when I try to perform Abaqus/implicit analysis, a problem comes up. I can enter tabular data of frequency but I cannot enter FFT values because Abaqus does not accept complex numbaers in amplitude column.

I would be grateful if anybody could give me a hint of how to solve this issue. I look forward to hearing from you.

 

Best Regards, 

Hanson

equivalent stress for Tsai-Wu yield criteria

 

Greetings,

As Tsai-Wu criteria is F(ij)sigma(i)sigma(j) + F(i)sigma(i) = 1.
In my cases, i will appiled yield strength as for the F(ij) and F(i) and then i will applied for the hardening process. but the problem is may i know what is the equivalent stress one yield is start as i want continue with the hardening process which in term of equivalent stress corresponding to the equivalent plastic strain.

how we choose our reference equivalent stress: is't we choose one of the yield strength(compression / tension in direction 1 or2 or 3) of the material?

RE: USDFLD and *INITIAL CONDITION, TYPE=FIELD

 

Hello,

Please check Abaqus Analysis User’s Guide

34.2.1 Initial conditions in Abaqus/Standard and Abaqus/Explicit

            Defining initial stresses

And Abaqus Keywords Reference Guide. Initial conditions are dependent on the type of analysis,

 

If you want more explanation, you should try describing the problem to solve rather than asking what=where. Many other users browse the mailing lists and a description might help.

Hi,

I need to define initial condition in input file in Abaqus,
I don't know where to place initial condition and I don't know what to writ in the line just after :
*INITIAL CONDITIONS, TYPE=STRESS

Could you help in this please?

Thank you in advance.

Regards,
Khouloud.

Unexpected shear stresses from friction model

 

Hi guys, 

I am having problems establishing a simple 2D friction model in Abaqus between two rectangular elements (concrete and steel). I am using a vertical contact pressure on the steel surface and a frictional coefficient between the two surfaces of 0.45. 
I have defined the frictional coefficient in the contact properties as a "Penalty" and used "Normal" and "Tangential behaviour". At last I have defined a horizontal displacement to the steel part. 

When I run the model and plot my results I get a linear displacement curve which is expected but my shear stress also happens to be linear which it shouldn't. Also, the shear stresses are zigzagged and therefore non-monotonic which is a problem. My objective in this model is to get a plot similar to Figure 12-5 in the "Getting Started with Abaqus" manual. 
Can you help me? 

Note: I am sure that my BCs are correct. I have run the model with 200 increments and used a fine mesh too.

Material definition

 

Hello everybody, For my thesis I'm working with a material that shows very different tensile and compressive properties. I'm relatively new to Abaqus and I'm having some difficulties in getting the material properties into my model. In compression: E = 1400MPa until average stress is 62MPa then stiffness gets lower until the strain is -0.13. At this point the E = 130 MPa until the material collapses at 0.3 strain. IN tension: E = 8400MPa until brittle failure at 130MPa. What would you guys suggest on how I could define this kind of material in Abaqus? Thanks in Advance!
