This course covers a range of topics, all aimed at structural designers and engineers.
Composite systems include many more factors than conventional metallic structures.
The objective of this course is to break down the composite analysis process into clearly defined steps, give an overview of the physics involved and show how to successfully implement practical solutions using Finite Element Analysis.
Moving to composite structures will allow you to explore:
Composite materials span:
The challenge for the designer and analyst is to make decisions on the type of idealization and level of detail required in the Finite Element Analysis. Your design may include:
Analysis is further complicated by:
We can help you plan a strategy for dealing with these challenges.
All attendees on the course will be able to download a fully functioning Composite Stiffness and Strength Calculator, together with user guide.
Many past attendees have found this tool a useful supplement to post processing available in their usual Finite Element solution. Attendees will be entitled to future upgrades.
