Basic knowledge of Ansys Mechanical

Software used
Ansys Mechanical

Benefits
  • Carrying out working load analyses for reinforced concrete
  • Bearing capacity and a settlement analysis with several soil models
  • Identifying material parameters and being able to input them correctly
  • Mastering efficient control of non-linear computation with several geo-mechanical models

Description

The fields of mechanical and civil engineering are becoming more intertwined due to the increasing complexity of projects in fields such as structural engineering and the energy sector. This higher complexity results in the increasing importance of a realistic description of geo-mechanical materials and concrete in practical applications. To accurately predict both the bearing capacity and soil settlements, a realistic description of geo-mechanical materials and their implementation in Numerical Simulations is needed. Realistic modeling of concrete materials is necessary to optimize the dimensions of concrete foundations or concrete stabilization walls. The actual interaction between concrete and soil must be taken into account for optimal design.

In this course, you will learn how to perform bearing capacity analysis for reinforced concrete and settlement analysis with various soil models. You will recognize material parameters and define them in Ansys Mechanical. Practical exercises enable you to quickly familiarize yourself with foundation modeling. You will acquire the basic knowledge for controlling nonlinear foundation analysis. The training is intended for civil and mechanical engineers working in interdisciplinary teams who want to be able to model the behavior of geo-mechanical materials for product development and construction projects based on realistic computer simulations.

Do you have questions on the training?

When will I receive the final confirmation for my training booking?

Straight after you sign up, an automatic confirmation of receipt will be sent to the email addresses you provided. Once you have successfully verified the data you provided, you will receive your personalized sign-up confirmation, containing further information on course fees, the billing address, etc., by email within two to three working days.  

As soon as the minimum number of attendees has been reached, you will receive a final training confirmation containing further information. If you have booked an on-site training, we recommend that you wait until you have received this final confirmation before booking your travel and accommodation.

If the minimum number of attendees is not reached, we reserve the right to cancel the training seven days before it is due to start at the latest. We are happy to inform you on changing your booking to an alternative date. Please note that we accept no liability for hotel or travel bookings that attendees have already made.

When is the sign-up deadline for a training?

Training places will generally be allocated based on the order in which attendees sign up. For this reason, we always recommend booking for your desired date as early as possible.

As long as a coures still has free places, it can be booked.

At what time do the training courses begin and end?

Usually the training courses start at 9:00 am and end at 5:00 pm of the respective local time. The actual course times will be stated in the booking confirmation. Please note that, depending on the training host, there may be a possible time shift between your and the provider's local time. Therefore all local times are provided with the valid time shift to Greenwich Mean Time (GMT).
