DNV CG-0128 Plate Buckling (2015)

DNV-CG-0128 (October 2015) is a DNV Class Guideline focused on the buckling and ultimate strength capacity of structural components. SDC Verifier implements the Closed Form Method (CFM) from Section 3, tailored for unstiffened plates subject to compression and shear.

Key features:

• Uses material data (yield/tensile) and partial safety factors per the standard.
• Automatically translates element stresses into local plate directions (X, Y, XY).
• Supports conservative assessment options such as absolute shear and averaged plate stresses.
• Integration with Panel Finder enables automatic detection of sections and plate dimensions.
• Plate thickness can be scaled via Thickness Factor or manually overridden.

The guideline applies to ships, offshore units, and plated structures built to DNV-RU-SHIP and DNV-RU-OU standards.
