  COSMOSWorks™ Nonlinear
| Course Duration: |
2 days
|
| Course Description: |
This course will raise your COSMOSWorks FEA skills to the next level! It offers hands-on experience on the use of COSMOSWorks nonlinear module. The 2-day course provides an overview on a wide range of nonlinear structural/mechanical analysis topics. You will learn how to deal with the models that exhibit large displacements and/or yielding, discuss and practice the use of many material models available in COSMOSWorks and, most importantly, how to drive a non-linear analysis to successful completion.
|
| Prerequisites: |
Mechanical design experience.
Basic understanding of Finite Element Analysis.
Should have attended SolidWorks Mechanical or Product Design training course and COSMOSWorks Designer Training. Knowledge of, or experience with the Windows™ operating system.
