DNV CG-0128 Plate Buckling (2023)

DNV-CG-0128 provides a robust methodology for evaluating the buckling and ultimate strength of metallic plate structures, particularly those in ship hulls and offshore units. The implemented section (Section 3, Closed Form Method) supports the verification of unstiffened plates under compressive and shear loads.

This update aligns with the December 2023 edition of the guideline and includes configuration for assessment method types, partial safety factors, and automated panel recognition.

Key features:

• Calculation of buckling capacity based on CFM
• Optional use of average plate stresses and element-wise values
• Inclusion of thickness scaling and stress translation into plate-local axes
• Material data checks and safety factor customization
• CSR method support for plate dimension approximation
