Explicit Model for a Spring

$0.00

Description

There are two types of simulations in Abaqus to simulate a process which are 1- Implicit 2-Explicit model. Implicit models are helpful in simulating a process close to a steady-state. On the other hand, Explicit models are good to simulate fast models with element deletion.

Explicit Vs Implicit models:

Implicit models:

Implicit models have a large time increment size and are capable of modelling processes with larger step time. The advantage of using implicit models is creating models that require a longer time in the real process. This is because of the element formulations used in this technique. The most common examples of implicit models are rolling processes, low deformation processes and satellite movements in space. However, there are problems which make it impossible to use implicit models for some processes. Models that require sudden change and large deformation require small time increment size. Since the required time to solve each increment is large, it is not affordable to create models with numerous increments. Consequently, implicit models are not good for models like explosions and some types of forging.

Explicit models:

Explicit models have smaller time increment size compared to implicit models. In fact, explicit models are the combination of lots of static models to minimize the effect of acceleration in simulation. The time increment is small enough to ignore the effect of acceleration in each increment. However, the effect of acceleration excites in the whole process. Since the time increment is small it is possible to create models with large deformation and sudden changes. The most common examples of explicit models are explosions, large deformation processes, and models with complex surface contacts.

More details about this product:

There are many kinds of processes that require the use of explicit models to solve. Based on the process the model can be time-consuming or complex to simulate. Thus, the best way to start is to create a very simple and interesting model. A spring response after releasing the pressure requires a short time to solve and has interesting results. If you found this model too easy, you can go for the next step which is simulating the damage model:

An Example For a Damage Explicit Model (1)

An Example For a Damage Explicit Model (2)

In this model, we use a simple example to simulate the spring response after releasing it. Here, we just show a simple explicit model. We don’t assume it is a completely elastic material and we don’t use mass scaling for this example.

In this product, we only give an example to help you with using the explicit model. We avoid giving too many details so you can easily use the product. Furthermore, You will learn how to use this option in Abaqus to simulate super large deformation processes. In this product, you can find the following files:
