Hi -
I'm constructing a FEA model of a landing gear for a drop test via ABAQUS. How do you determine/find data on the Rayleigh Damping coefficients for an aluminum structure, specifically a skid landing gear. After assessing my simulation, it's clear that I need to include damping in my FEA...

How do you determine/find data on the Rayleigh Damping coefficients for an aluminum structure, specifically a skid landing gear. After assessing my simulation, it's clear that I need to include damping in my FEA model - but I do not know how to obtain the proportional damping coefficient...
I am wondering if any of you use matplotlib for your python codes that are coupled with abaqus. I really want to load matplotlib onto the abaqus-python interface. I'm using abaqus 6.12, which has python 2.6. Also, I'm using Windows 64 bit.
However, when I download the matplotlib for python...
Hello everyone,
I have limited experience with abaqus. Previously, I would use a static analysis and apply loads in the ramp format. Now I'm doing a dynamic/explicit analysis, and I cannot find the ramp feature. How do you apply a ramp load in dynamic/explicit analysis?
With static...
I was wondering if it is possible to write a python script that locates the maximum stress in a simulation where the stress distribution varies with time and position.
Basically I am writing a parametric simulation. Many geometric parameters (length, thicknesses, radii, etc) can be varied...
I am finishing up a BS in Aerospace Engineering from a U.S. university and trying to decide whether to go for an MS in AE or go to Law School. My questions are below.
Which degree (MSAE or JD) yields a higher salary?
What is the better career path - engineering or law?
In general, which is...
I'm modeling a contact problem by applying force to a reference point on a rigid joint, which is in contact with a deformable leg component. I set up a surface-to-surface interaction and input a load to the reference point on the joint. In general everything works as I would predict; the force...
Hi everyone:
I have been running a contact simulation that has had convergence problems. I was getting the error message: Convergence judged unlikely. In order to make my simulation converge, I have been increasing the damping coefficient to a very large number. I have went to Interaction...
IceBreakerSours, Thank you.
You're post makes sense and is consistent with other research I've been doing on this. I prefer option 1. I understand that option 2 is a good brute force was of applying the moving pressure to the rod, but I have limited experience with FORTRAN.
However, I now...
That is indeed part of what I want but I want the pressure moving with respect to time also. So, I have the pressure's amplitude and location change with time.
A physical example would be modeling a road with tires moving on top of it, which causes a moving pressure. Except now the...
Any ideas? Surely someone has had to model a moving pressure before.
I was wondering if there is a common method on how to do it.
Could I prescribe a pressure over the entire object being analyzed, then implement a "user-defined" pressure distribution such that the distribution is 1 at the...
hello,
I am running a simulation in which one of the parts is a rigid body. I have a quick question regarding the defining of reference points. Basically, when I try to run my job, I get an error message saying "The rigid part instance Part-4-1 is missing a reference point".
It makes sense...
I have bar that extends in and out of a socket. At the contact points between this socket and rod, a moment and forces are induced. We do not know exactly how the moment/forces are imposed onto the structure, we just know the area of contact, its magnitude, sign, and time-variation. I want to...
I am beginning to run FEA simulations, and I am wondering the most common way to apply loads to a structure in ABAQUS. I see that concentrated loads are the 1st option on ABAQUS, but clearly this will yield an erroneous stress field across the solid since the point load is unrealistic and will...
