I want to simulate the interference fit ,the interferernce=-1,then I define a tabular,(0,0;1,1). and the first step period is 1, I want to know whether the last interference is -1 at the last time .
Then i check the "help doqument",it say"If the analysis time in a step is less than the earliest time for which data exist in the table, Abaqus applies the earliest value in the table for all step times less than the earliest tabulated time. Similarly, if the analysis continues for step times past the last time for which data are defined in the table, the last value in the table is applied for all subsequent time."
Can someone explain to me ,thanks very much.
If you enter a table like
0.3, 5
0.8, 9
then for time values smaller than 0.3, a value of 5 is taken, for time values latger than 0.8, the value is 0.9. That's all it means.
Hi HU
Use the tabular definition method to define the amplitude curve as a table of values at convenient points on the time scale. Abaqus interpolates linearly between these values, as needed. Several examples of tabular input are shown in table1.(Abaqus 6.13 Documentation)
@Martin Baeker，Thanks , if i define the tabular is 0,0; 1,1 . then the first step is 0.2, how much the value is ? does it caculate linearly between 0and 1?
If everything fails, read the manual.
Abaqus interpolate between two points that you have defined. in your example
0, 0,
1.0, 1.0
Then at the time of 0,2 the amplitude is 0.2 , a simple linear interpolation.
The variation of an amplitude with time can be specified in several ways. See the following link:
