DNV-RP-C208: Determination of structural capacity by non-linear finite element analysis methods
A 3-day training course in DNV-RP-C208, a recommended practice established to determine structural capacity by non-linear finite element analysis methods
Description of recommended practice DNV-RP-C208
DNV-RP-C208 is intended to give guidance on how to establish structural resistance by use of non-linear finite element (FE) methods. The recommended practice (RP) deals with determining the characteristic resistance of a structure or part of a structure in a way that fulfils the requirements to ultimate strength in DNV standards. The objective of the RP is that analyses carried out according to the recommendations given in the RP will lead to a structure that meets the requirements to the minimum safety margin in the governing structural standard.
Course description
The course offers an introduction to the philosophy of DNV-RP-C208, fundamental principles of FE-analyses, and general requirements to FE-analyses. Central topics in the RP on how to determine structural capacity for different failure modes with FE-analyses are lectured through a combination of theory and examples.
Course objective
After completing the training course, you will know the background, objective and content of DNV-RP-C208. The participants will be introduced to methods for how to determine structural capacity by non-linear FE-analysis methods according to the RP.
