This course emphasizes practical skills and techniques that are needed for analyses with Abaqus/Explicit. The course uses examples derived from actual industrial applications to reinforce the concepts and issues discussed in the lessons.
The course covers the following topics:
- The explicit dynamics method
- General contact
- Automatic mass scaling for impact problems
- Automatic mass scaling for quasi-static problems
- Using Abaqus/Explicit and Abaqus/Standard together to solve difficult problems, including results transfer and co-simulation
- Modeling high-strain-rate deformation and failure
- Output filtering
- Managing large models
Intended Audience
This course is recommended for relatively new Abaqus/Explicit users and Abaqus/Standard users who want to learn Abaqus/Explicit, regardless of industry or application.

Training Methods
Choose from three different training methods available to you
Group / Classroom Training
Receive SIMULIA Abaqus/Explicit Advanced Topics training in a group in a traditional classroom environment. Courses can be taken in one of our training locations in the UK, Ireland, US or Canada using DS approved training content and methodologies.
Advantages
- Cost effective training method.
- Leave the office to concentrate on learning.
- Learn more through group questions and feedback.
Live Online Training
With online training you will experience an interactive learning environment where you can give feedback, gain access to the training files and get time to work on training exercises.
Advantages
- Online courses can maximise convenience and save on travel expenses.
- More effective than video based training, with recorded videos learners are often not as focused on the training and skip exercises.
On-Site Training
Receive training at your place of work. This style of flexible training is perfect for teams or individuals who are faced with a specific challenge and require personalized courses with on-the-job coaching.
Advantages
- Use our state-of-the-art mobile classroom at your facility.
- Bring your team up to a consistent level of knowledge by having them take the same training at the same time.
- Benefit from flexible scheduling options.
