Why Choose SDC Verifier for IACS UR S35 Compliance

open benchmarks to verify design

Automated Plate Buckling Checks

Instantly perform direct strength analysis on unstiffened plates based on IACS UR S35 guidelines — no spreadsheets required.

Accurate Stress Conversion

Built-in logic transforms element stresses into plate directions (X, Y, XY) automatically for consistent, standards-aligned results.

Seamless Section Recognition

Panel Finder detects and measures plate sections across complex ship structures — ready for immediate buckling evaluation.

Compliance Without Guesswork

Built-in safety factors, slenderness coefficients, and plate dimensions ensure your model meets IACS classification requirements out of the box.

Traceable Results and Reports

Generate transparent, standards-based reports with visual plate plots, flow tables, and critical buckling zones highlighted.

About Standard

The IACS UR S35 standard—issued by the International Association of Classification Societies—defines mandatory rules for evaluating the buckling strength of unstiffened plates used in ships and offshore structures. It ensures that plate elements can withstand compressive, in-plane, and shear forces without failure.

Objective: Prevent buckling-related failures in marine and offshore environments by establishing a uniform strength assessment methodology.

Scope of Application:

Hulls of ships and offshore platforms
Bulkhead, deck, and cargo hold plates
Oil rigs, FPSOs, and naval structures

Engineering Impact: By applying UR S35, naval architects and structural engineers can:

Optimize plate thickness while maintaining safety margins
Identify failure-prone regions early in the design
Align with latest IACS classification society requirements

The 2023 revision (Corr. 1, Sep. 2024) reflects updated methods and safety factors for robust structural integrity in demanding offshore conditions.

Frequently Asked Questions

What is IACS UR S35 Plate Buckling?

It’s a standard developed by the International Association of Classification Societies to evaluate the buckling strength of unstiffened plates in ships and offshore structures under various loading conditions.

Which industries benefit from this standard?

Primarily shipbuilding and offshore engineering — particularly naval architects and structural engineers working on hulls, bulkheads, decks, oil rigs, and FPSOs.

Does SDC Verifier automatically recognize plate sections?

Yes. The Panel Finder tool in SDC Verifier detects and defines sections and plates, streamlining the setup for buckling checks.

Can I edit plate dimensions manually?

Yes, you can override default values and define plate thickness manually if needed.

How do I enable IACS UR S35 in SDC Verifier?

Navigate to Standards → Main → Other → IACS UR S35 Plate Buckling (2023). Custom settings can be adjusted from the Help panel.
