How do you plot amplitude in Abaqus?
You can launch the Amplitude Plotter by selecting Plug-insToolsAmplitude Plotter from the main menu bar in the Interaction module or the Load module. To plot amplitude data, select one or more amplitude rows in the top half of the dialog box and click Plot.
What is amplitude in Abaqus?
Define an amplitude curve. This option allows arbitrary time (or frequency in an Abaqus/Standard analysis) variations of load, displacement, and other prescribed variable magnitudes to be given throughout a step.
How is Abaqus time period defined?
If you do not specify a time period, Abaqus/Standard defaults to a time period in which “time” varies from 0.0 to 1.0 over the step. The “time” increments are then simply fractions of the total period of the step.
What is step in Abaqus?
Defining steps A step is any convenient phase of the history—a thermal transient, a creep hold, a dynamic transient, etc. In its simplest form a step can be just a static analysis in Abaqus/Standard of a load change from one magnitude to another.
How do you change the amplitude in Abaqus?
Display the Edit Amplitude dialog box as described in “Selecting an amplitude type to define,” Section 57.3. Click the arrow to the right of the Time span field, and specify how you want to define the amplitude as a function of time: Select Step time for time that is measured from the beginning of each step.
What is ramp amplitude in Abaqus?
This parameter defines the default amplitude variation for loading magnitudes during the step. Set AMPLITUDE=RAMP if the load magnitude is to vary linearly over the step, from the value at the end of the previous step (or zero, at the start of the analysis) to the value given on the loading option.
How do you change the time on Abaqus?
Changing the period of a step
- Locate the Active Steps/Frames dialog box. From the main menu bar, select ResultActive Steps/Frames.
- From the lower portion of this dialog box, click the value in Period column for a step, then enter a new value in the field.
- Click Apply.
What is SDI in Abaqus?
Abaqus/Standard contact information is available for any iterations that are followed by (SDI) (Severe Discontinuity Iteration) in the Job History tree. Use the contact information to locate regions in your model where Abaqus could not establish the correct conditions.
How do I reduce my step time in Abaqus?
Several points to reduce the computation time for incremental forming via ABAQUS/Explicit:
- increase tool speed.
- mass scaling, either automatic or fixed. or target dt=5E-6, for example.
- control output #
- use symmetry for model if possible.
- use rigid tool.
- integration point # through sheet thickness.
What are steps in Abaqus?
A basic concept in Abaqus is the division of the problem history into steps. A step is any convenient phase of the history—a thermal transient, a creep hold, a dynamic transient, etc. In its simplest form a step can be just a static analysis in Abaqus/Standard of a load change from one magnitude to another.
What is the use of amplitude in Abaqus?
Amplitude option is used to express the field variable as function of time. In default the amplitude value be (Ramp). In Abaqus we can choose any one of the following options:
How do you use Abaqus interpolation?
ABAQUS interpolates linearly between each time interval. You must specify the fixed time (or frequency) interval at which the amplitude data will be given, . You can also specify the time (or lowest frequency) at which the first amplitude is given, ; the default is =0.0.
When does Abaqus apply the earliest value in the table?
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.
What is the difference between Abaqus/Standard and abqus/explicit?
By default in Abaqus/Standard , if the time derivatives of the function must be computed, some smoothing is applied at the time points where the time derivatives are discontinuous. In contrast, in Abaqus/Explicit no default smoothing is applied (other than the inherent smoothing associated with a finite time increment).
